Benjamin Eager (born January 22, 1984 in Ottawa, Ontario) is a Canadian professional ice hockey left winger who currently plays for the Chicago Blackhawks of the NHL. He attended Immaculata High School in Ottawa.

Eager was drafted in the 1st round, 22nd overall by the Phoenix Coyotes in the 2002 NHL Entry Draft. He was later traded by the Coyotes along with Sean Burke and Branko Radivojević to the Philadelphia Flyers for centre Mike Comrie.

The 2006–07 NHL season would see Eager lead the league in penalty minutes, even though he only played 63 games. That same season, he also won the Pelle Lindbergh Memorial as the Flyer who has most improved from the previous season, as voted by his teammates.
