The ninth season of animated television series Family Guy first aired on the Fox network in eighteen episodes from September 26, 2010, to May 22, 2011, before being released as two DVD box sets and in syndication.

Family Guy follows the dysfunctional Griffin family—father Peter, mother Lois, daughter Meg, son Chris, baby Stewie and dog Brian, all of whom reside in their hometown of Quahog.

The season received a mixed reception from critics, who called it "a mixture of laugh out loud gags, groan inducing puns, and astonishing 'I can't believe they got away with that' statements.

The showrunners for the ninth season were Hentemann and Callaghan,[12] who oversaw the series's transition into 720p high definition in the premiere of the ninth-season episode "And Then There Were Fewer".

[8] As production began, Callaghan, Andrew Goldberg, Mark Hentemann, Patrick Meighan, Brian Scully, Chris Sheridan, Danny Smith, Alec Sulkin, John Viener and Wellesley Wild all stayed on from the previous season.

Recurring directors Dominic Bianchi, Greg Colton, John Holmquist, Brian Iles, Jerry Langford, Pete Michels, James Purdum, Cyndi Tang and Julius Wu all stayed with the show from the previous season.
