Susan McInnis (born June 18, 1963, in Charlottetown, Prince Edward Island) is a Canadian curler.

McInnis was back in 1996 as a skip and led her PEI rink, which included Kathy O'Rourke, Tricia MacGregor (Affleck) and Leslie Allan (MacDougall), to a 6–5 record.

McInnis then joined the Tammi Lowther rink at third, and played in the 1998 Scott Tournament of Hearts, finishing with a 4–7 record.

McInnis did not return to the Hearts until 2003, throwing lead stones for Suzanne Gaudet (now Birt), who was fresh from winning two Canadian Junior championships.

However, they buckled under pressure in the playoffs, losing to the defending champion Colleen Jones rink in the 1 vs. 2 game, and then to Newfoundland and Labrador's Cathy Cunningham in the semi-final.
