The Senator's logo is officially the head of a Roman general, a member of the Senate of the Roman Empire, projecting from a gold circle. The original, unveiled on May 23, 1991, described the general as a "centurion figure, strong and prominent" according to its designer, Tony Milchard. The original had the words "Ottawa Senators" within the circle which was slightly revised in 1996 to remove the team name from the gold circle and replace it with laurels. In 2008, the Senators unveiled a new primary logo which was an update of the old secondary logo. According to team owner Eugene Melnyk, the new logo "represents strength and determination."

The Senator’s logo is officially the head of a Roman general, a member of the Senate of the Roman Empire, projecting from a gold circle. The logo is slightly more upright and the additional squint in the eyes makes him more stoic. Mirroring the shift toward visor use in the NHL, his helmet also protects more of his face.
1998 - 2007
The logo underwent a slight transformation, as the wordmark “Ottawa Senators” disappeared in favor of laurels. The rest of the logo did not change.
1993 - 1997
