Who is Rick's son-in-law and Morty's father in "Rick and Morty"?

Rick's son-in-law and Morty's father in "Rick and Morty" is Jerry Smith. Jerry is married to Beth Smith, Rick Sanchez's daughter, making him Rick's son-in-law and Morty's father.

Jerry is portrayed as insecure, frequently unemployed or underemployed, and often outmatched by Rick's scientific brilliance. His ordinary, anxious personality contrasts with Rick's reckless adventures, creating much of the show's family conflict. Jerry strongly disapproves of Rick's influence over Beth, Morty, and Summer, even though he is often unable to stop Rick from involving them in dangerous interdimensional situations.

A common mix-up is calling Rick Morty's father because Rick is the character who most often accompanies Morty on adventures. Rick is actually Morty's maternal grandfather. Beth is Morty's mother, while Summer Smith is his older sister. The series features many alternate realities and alternate versions of the family, but Jerry remains the standard canonical answer to this description.
