Which character is Danny Tanner's childhood best friend on Full House?

Joey Gladstone is Danny Tanner’s childhood best friend on Full House. Played by Dave Coulier, Joey is introduced as one of the two adults who move into Danny’s San Francisco home after Danny’s wife, Pam, dies.

Joey helps Danny raise D.J., Stephanie, and Michelle, making him an important part of the show’s unusual extended household. His career as a stand-up comedian supplies many storylines, including his famous impressions of cartoon characters such as Popeye and Bullwinkle. Although Joey is Danny’s longtime friend, the series also develops a close friendship between Joey and Jesse Katsopolis.

Viewers sometimes confuse Joey’s relationships because Jesse is Danny’s brother-in-law and Joey’s close adult friend. Jesse is also the children’s uncle, while Joey is their honorary “Uncle Joey.” Nick Katsopolis is Jesse’s father, and Steve Hale is primarily connected to D.J.’s later romantic storylines. Joey’s childhood friendship with Danny is therefore the canonical answer, not one of the other men listed.
