Who Voices Finn in Adventure Time: Side Quests?

Finn the Human is the heart of every Adventure Time story, and Adventure Time: Side Quests puts him back at the center of the action alongside Jake. Because the series revisits a younger Finn and Jake during their classic adventuring era, one of the first questions fans ask is who is providing Finn's voice this time around.

The definitive answer lives in the official series listings. Adventure Time: Side Quests has a dedicated page on Disney+, and cast credits are also tracked on Rotten Tomatoes' cast and crew page. These are the authoritative sources for the current voice cast, since streaming and television listings are updated as new episode batches are released.

To understand why Finn's voice matters so much in Side Quests, it helps to look at the character's voice history in the franchise.

Finn's Voice Across the Adventure Time Franchise

Finn's voice is unusual among animated leads because the character was voiced by a growing performer for more than a decade. Jeremy Shada began voicing Finn as a young actor and continued through the original series' entire run, meaning Finn's voice naturally matured alongside the character.

Because Side Quests returns to an earlier chapter of Finn and Jake's adventuring years, the show's voice direction faces an interesting creative question: how should a younger Finn sound? The series presents Finn in relatively independent, eleven-minute episodic adventures across the Land of Ooo, so the vocal performance needs to match the energetic, wide-eyed hero fans remember from the classic era.

Why This Matters

Side Quests is best described as a series focused on Finn and Jake's earlier adventures, not a strict prequel. Community discussions note the "prequel" label is debated, so treat the show as standalone side adventures within the classic era.

The Full Side Quests Cast Picture

While Finn's voice actor draws the most searches, Side Quests is an ensemble series. The official promotional material confirms that classic elements return, including encounters with the Ice King, and the series description highlights Finn and Jake's new episodic adventures across Ooo.
