The 2011 Manly Warringah Sea Eagles season was the 62nd in the club's history. Coached by Des Hasler and co-captained by Jamie Lyon and Jason King, they competed in the National Rugby League (NRL) 2011 Telstra Premiership, and finished the regular season in second place (out of 16 teams). The Sea Eagles then qualified for the NRL grand final, in which they defeated the New Zealand Warriors, claiming the club's eighth first-grade premiership.
