Understanding the voice cast behind Rick and Morty requires looking at a decade of chaotic interdimensional adventures and a major behind-the-scenes casting overhaul. For the first six seasons, co-creator Justin Roiland handled the vocal duties for both title characters, alongside a core ensemble of steady television veterans. Following a high-profile transition in production, Adult Swim brought in new talent to keep the portal gun firing.
Knowing who voices your favorite Smith family members and galactic side characters clarifies how the show maintains its distinct audio identity. This breakdown maps out the voice actors across the series eras, highlighting main cast members, recurring guest stars, and the reality of the vocal transition.
The Core Smith Family Cast
While the lead characters underwent a massive shift, the rest of the immediate Smith family remained stable from the very beginning. Their performances anchor the show amid cosmic absurdity.
- Chris Parnell as Jerry Smith: Parnell brings his signature milquetoast delivery to Morty and Summer's insecure, well-meaning father. Best known for Saturday Night Live and Archer, Parnell has voiced Jerry through every existential crisis and divorce plot without interruption.
- Spencer Grammer as Summer Smith: Grammer voices Morty's older sister, balancing teenage cynicism with surprising action-hero competence. Her sharp comedic timing has defined Summer's evolution from a typical sitcom sibling to a hardened multidimensional survivor.
- Sarah Chalke as Beth Smith and Space Beth: Chalke, famous for her roles in Scrubs and Roswell, voices the sharp-tongued matriarch as well as her interstellar clone, Space Beth. Chalke manages to differentiate the domestic vet from her galactic counterpart through subtle shifts in cynicism and warmth.
Seasons 1 Through 6: The Roiland Era
During the first six seasons, co-creator Justin Roiland performed the voices of both Rick Sanchez and Morty Smith, alongside dozens of background aliens, alternate-universe variants, and minor characters like Mr. Poopybutthole.
Roiland's improvisational style shaped the early rhythm of the show, characterized by stutters, burps, and manic energy. However, following legal controversies and subsequent termination by Adult Swim in early 2023, the production team faced the monumental task of recasting two iconic, highly specific voices without losing the soul of the series.
Season 7 to Present: The New Lead Actors
To fill the massive void left by Roiland, Adult Swim conducted an extensive, secretive audition process to find performers who could match the cadence and tone of the original recordings. They ultimately split the dual role between two distinct actors.
- Ian Cardoni as Rick Sanchez: Cardoni stepped in as the voice of the cynical, genius scientist starting with season seven. Finding someone who could hit Rick's raspy delivery without sounding like a cheap imitation proved difficult for the casting directors, but Cardoni's precision allowed the show to transition with minimal friction for most viewers.
- Harry Belden as Morty Smith: Belden took over the role of the anxious, easily manipulated grandson. Belden captures Morty's trademark high-pitched panic and moral objections, keeping the dynamic between the grandfather-grandson duo intact.

Key Recurring and Guest Voice Actors
Beyond the primary family, Rick and Morty relies heavily on a rotating roster of recognizable comedic talent and dedicated voice actors to populate its multiverse.
- Tom Kenny as Squanchy and Gene: Veteran voice actor Tom Kenny (SpongeBob SquarePants) voices several recurring characters, including the feral feline Squanchy and the long-suffering neighbor Gene.
- Kari Wahlgren as Diane Sanchez: Wahlgren provides the voice for Rick's deceased wife, Diane, whose tragic backstory drives much of Rick's emotional motivation throughout the later arcs. Wahlgren also voices the spaceship's onboard artificial intelligence.
- Keith David as President Curtis: The distinguished actor brings gravitas and deadpan humor to the recurring role of the President of the United States, who frequently engages in petty turf wars with Rick.
- Dan Harmon as Birdperson: Co-creator Dan Harmon voices Rick's stoic, tragic best friend, Birdperson (later known as Phoenixperson), anchoring several of the series' heaviest dramatic beats.
