What is Rick's last name in "Rick and Morty"?

Rick’s last name in Rick and Morty is Sanchez. His full name is Rick Sanchez, the eccentric scientist whose interdimensional adventures drive the animated series.

Rick lives with his daughter Beth Smith, her husband Jerry, and their children Morty and Summer. Because Beth uses the surname Smith after marriage, viewers sometimes see the family described as the Smith household, while Rick retains Sanchez as his family name.

The show follows multiple versions of Rick across an infinite multiverse. The central version commonly identifies himself as Rick C-137, connecting his name to the dimension associated with his backstory. Other Ricks also appear, and their personalities and histories can differ, but “Sanchez” remains the character’s recognizable surname.

Rick and Morty premiered on Adult Swim in 2013 and was created by Dan Harmon and Justin Roiland. Rick is voiced by Ian Cardoni from season seven onward, following Justin Roiland’s work in the first six seasons. The surname is also part of the series’ larger family and identity themes, especially Rick’s complicated relationship with Beth and Morty.
