Jonathan Groff sings as Kristoff in Frozen and voices the character in both Frozen films. He performs Kristoff’s featured songs, including Reindeer(s) Are Better Than People and Lost in the Woods.
This guide explains which songs Groff sings, how his voice work differs from the other cast members, and where Kristoff’s music appears. It also clears up a common mix-up: the singer playing Kristoff is not the singer behind Hans or Olaf.
who sings as kristoff in frozen: The direct answer
Jonathan Groff is Kristoff’s singing and speaking voice in Disney’s Frozen (2013) and Frozen II (2019). Groff performs the character’s dialogue and songs, so the voice you hear as Kristoff is his throughout both films.
Kristoff is the ice harvester who travels with Anna, Elsa, Olaf, and his reindeer Sven. His songs mix humor with emotion: one is a short comic exchange with Sven, while another is a dramatic 1980s-style power ballad. Groff performs both in character, rather than being replaced by a separate singer for the musical numbers.
The shortest answer is simple: if you are asking who sings for Kristoff, it is Jonathan Groff. If you are asking which songs belong to Kristoff, the two most prominent are Reindeer(s) Are Better Than People and Lost in the Woods.
Who is Jonathan Groff?
Jonathan Groff is an American actor and singer known for work in musical theater, film, television, and voice acting. His stage background is a natural fit for a Disney musical: he can deliver dialogue, shape a character through song, and make the musical performance feel like part of the story.
Before Frozen, Groff earned attention for playing Melchior Gabor in the Broadway musical Spring Awakening. He later appeared on Broadway as King George III in Hamilton, a role that also introduced his voice to audiences who may not have known his screen work.
His screen roles include Jesse St. James in the television series Glee and FBI agent Holden Ford in Mindhunter. Those performances show a different side of his acting, but the key fact for Frozen viewers is that Groff supplies both Kristoff’s voice and his singing.
Groff’s voice has a clear, expressive quality that suits Kristoff’s blunt humor and warm loyalty. He can make the character sound awkward without making him seem foolish, then shift into a more open, theatrical sound when the story calls for a full song.
Which songs does Kristoff sing?
Kristoff’s featured songs serve different purposes. Reindeer(s) Are Better Than People introduces his relationship with Sven through a short, comic number. Lost in the Woods gives him a much larger musical moment in Frozen II, revealing his feelings while playfully echoing the style of a dramatic pop-rock video.
| Song | Film | What happens | Best known for |
|---|---|---|---|
| Reindeer(s) Are Better Than People | Frozen | Kristoff sings to Sven during their journey. | A brief, funny glimpse of their close bond. |
| Lost in the Woods | Frozen II | Kristoff sings about feeling uncertain and separated from Anna. | A big, deliberately over-the-top rock-ballad performance. |
| Reindeer(s) Are Better Than People (Cont.) | Frozen II | A short return to the earlier song’s idea. | A small musical callback for fans of the first film. |
| Fixer Upper | Frozen | Kristoff is present during the trolls’ ensemble number. | A group song that includes the trolls’ advice about love. |
Reindeer(s) Are Better Than People
In the first Frozen, Kristoff sings this short song while speaking to Sven as if the reindeer can answer him. The scene captures their unusual partnership: Kristoff treats Sven as a trusted companion, even though Sven does not speak in human words.
The humor comes from the contrast between the song’s earnest delivery and its simple message. Kristoff says that reindeer are better company than people, which fits his guarded personality and his life spent traveling with Sven. The number is short, but it quickly tells you how much the two characters rely on each other.
The song’s title is often written as Reindeer(s) Are Better Than People. The parenthetical s reflects the wording used for the song, so you may see slightly different styling in articles or listings. It is the same Kristoff-and-Sven number, not a separate song.
Lost in the Woods
In Frozen II, Groff sings Lost in the Woods as Kristoff struggles to understand where his relationship with Anna is going. He wants to propose, but the journey keeps interrupting his plans, and he has trouble reading the changes around him.
The song turns that worry into a humorous musical sequence. Its dramatic arrangement and visual style recall classic arena-rock videos, while the lyrics stay rooted in Kristoff’s fear of losing his connection with Anna. The contrast makes the number funny without dismissing his feelings.
Lost in the Woods is also a major showcase for Groff as a singer. The role asks him to move from understated dialogue into a full, emotionally heightened performance. That shift helps explain why the song often stands out to viewers who remember Kristoff mainly as a dryly funny supporting character.
Other musical moments
Kristoff appears as part of the ensemble in Frozen’s Fixer Upper, a song led by the trolls. It is not a solo showcase in the same way as his featured numbers. The trolls sing about accepting a person’s flaws, while Anna and Kristoff react to the group’s enthusiastic matchmaking advice.
Frozen II also brings back the reindeer-song idea in a brief continuation. That return is a callback, not another full-length Kristoff ballad. If you are looking for the main song performances, start with Reindeer(s) Are Better Than People and Lost in the Woods.
Does Jonathan Groff sing Kristoff’s songs himself?
Yes. Groff performs Kristoff’s songs in the films. The songs are part of his character performance, not vocals assigned to a second actor while Groff only speaks the dialogue.
That distinction can be confusing in animated musicals. A character’s speaking voice and singing voice are sometimes performed by different people, especially when a production needs a particular vocal range or style. For Kristoff, however, Groff handles both sides of the performance.
Animation lets the filmmakers shape the character’s expression and movement around the recorded performance. Groff’s vocal choices help define Kristoff’s timing, warmth, and comic delivery, while the animators bring those qualities to life on screen.
How Kristoff’s singer differs from the other Frozen voices
Several actors perform the songs and dialogue for the central Frozen characters. Knowing the names makes it easier to identify who is singing in a particular scene, especially because the characters share songs and appear together in ensemble numbers.
| Character | Performer | Musical note |
|---|---|---|
| Kristoff | Jonathan Groff | Sings Reindeer(s) Are Better Than People and Lost in the Woods. |
| Anna | Kristen Bell | Sings featured songs including For the First Time in Forever and parts of Do You Want to Build a Snowman? |
| Elsa | Idina Menzel | Sings Let It Go and Into the Unknown. |
| Hans | Santino Fontana | Sings Love Is an Open Door with Anna. |
| Olaf | Josh Gad | Sings In Summer and When I Am Older. |
A common mix-up is to credit Love Is an Open Door to Kristoff because it is a duet between a male and female character. The male singer is Hans, voiced and sung by Santino Fontana; Anna is voiced and sung by Kristen Bell. Kristoff does not perform that song.
Another easy distinction is Elsa’s voice. Idina Menzel sings Elsa’s major musical numbers, while Kristen Bell performs Anna’s. Groff’s singing belongs to Kristoff, including his solo material and his parts in group scenes.
Why Lost in the Woods sounds so different from Kristoff’s first song
The two featured songs were written for very different moments. Reindeer(s) Are Better Than People is intimate and comic, with Kristoff essentially singing to his closest companion. Lost in the Woods expands the sound and scale because it expresses a bigger emotional conflict.
The musical change also supports the film’s characterization. Kristoff is often the practical person in the group, but he is not emotionally detached. His struggle to communicate with Anna gives the sequel a chance to show his vulnerability through an exaggerated musical style.
That change in tone does not mean a different actor is singing. Groff remains the performer. The arrangement, scene, and character mood change, while the voice belongs to the same actor in both films.
Where to hear the Kristoff songs
The songs appear in the films and on official Frozen soundtrack releases. Digital music services, physical soundtrack editions, and movie-music collections may list the tracks with slightly different punctuation or album formatting.
For the full performance, the film provides the scene, animation, and story context. A soundtrack track is useful if you want to listen without dialogue or picture, but an album’s exact track listing can vary by edition and territory.
Search for the film title together with the song title or Jonathan Groff’s name. That helps distinguish a soundtrack recording from covers, karaoke versions, fan edits, or unrelated songs with similar names.
Common questions about Kristoff’s voice and songs
Who sings Lost in the Woods?
Jonathan Groff sings Lost in the Woods as Kristoff in Frozen II. The number is his featured solo and is known for its dramatic, humorous rock-video presentation.
Who sings Reindeer(s) Are Better Than People?
Jonathan Groff sings it as Kristoff in the first Frozen film. Sven is the reindeer Kristoff addresses during the song, but Sven does not sing the human lyrics.
Is Kristoff’s singing voice the same as his speaking voice?
Yes. Jonathan Groff performs both Kristoff’s spoken dialogue and his singing in the films. There is no separate singing actor for Kristoff’s main songs.
Does Kristoff sing Love Is an Open Door?
No. Hans and Anna sing Love Is an Open Door. Santino Fontana performs Hans, and Kristen Bell performs Anna; Kristoff is not part of the duet.
Does Kristoff sing in Frozen II?
Yes. His main song in Frozen II is Lost in the Woods, and the film also includes a brief callback to Reindeer(s) Are Better Than People. Groff performs those moments as Kristoff.
Does Sven sing?
Sven does not deliver human lyrics in the films. Kristoff supplies the singing in their comic exchange, treating Sven as a conversational partner and interpreting the reindeer’s reactions.
What to listen for in Groff’s performance
Listen for how Groff changes Kristoff’s delivery to fit the scene. In the first film’s short reindeer song, the performance stays conversational and lightly comic. The joke works because Kristoff seems to mean what he sings, even as the situation is silly.
In Lost in the Woods, Groff uses a broader, more forceful style. The heightened vocals match the song’s large arrangement and visual joke, but the character’s uncertainty remains clear underneath. That combination keeps the scene connected to the plot rather than turning it into a disconnected parody.
It is also useful to notice the contrast between Kristoff and the other male characters. Hans’s duet with Anna is polished and romantic on the surface, while Kristoff’s songs reveal a less polished, more candid personality. The difference is part of how the musical numbers help distinguish the characters.
A useful detail about soundtrack credits
Song listings do not always make the character connection obvious. Some albums credit the performer, some emphasize the song title, and some use shortened titles. If a listing seems unclear, compare the song with the film scene or look for Jonathan Groff’s name alongside the Frozen soundtrack.
Also separate the original film performance from later covers. A singer performing Lost in the Woods on a stage, in a tribute recording, or in a fan video is not necessarily Groff. The original movie version features Groff as Kristoff.
One more point can prevent confusion: a song being performed by a character does not always mean that character leads it. Kristoff’s presence in an ensemble number such as Fixer Upper is different from his solo performances. For a direct answer about his own songs, the clearest examples remain Reindeer(s) Are Better Than People and Lost in the Woods.
Jonathan Groff voices and sings as Kristoff in both Frozen films. His featured songs include the comic Reindeer(s) Are Better Than People and Frozen II’s emotional, rock-styled Lost in the Woods.
To hear the performances in context, watch the two scenes or search the official soundtracks for the song titles and Groff’s name. Remember that Hans, not Kristoff, sings Love Is an Open Door with Anna.
