The 2005 Scott Tournament of Hearts, the Canadian women's curling championship, was held at Mile One Stadium in St. John's, Newfoundland and Labrador from February 19 to 27, 2005.

After the round-robin play, 4 teams were tied for the last playoff spot, and defending champion of the last 4 years, Colleen Jones was eliminated in her first tie-breaker match against New Brunswick's Sandy Comeau who would later lose to Jenn Hanna of Ontario.

Three of the four playoff teams were former national junior champions (Lawton in 2001, Jennifer Jones in 1994 and Scott in 1995), and the other was a runner-up (Hanna in 1998).

However, in a decision made in 2004, the Canadian Curling Association awarded the new contract to CBC, which had a higher bid than TSN.

Many Canadian fans were outraged come Tournament time, as they were disappointed with what many considered inferior coverage on the CBC as well as the scheduling problems.
