The 35-year-old Comeau led Dallas forwards with 106 hits while scoring 14 points (four goals, 10 assists) last season. Comeau has spent three of his 15 seasons with the Stars.
"Blake's approach to the game, coupled with his determination and physical presence on the ice, has been a tremendous asset for us over the past three seasons," general manager Jim Nill said Monday.
