Janice "Jan" Betker (born July 19, 1960, in Regina, Saskatchewan) is a Canadian curler.

Betker is best known for playing third on the Sandra Schmirler rink that won three world championships and an Olympic gold medal in the 1990s.

In 2019, Betker was named the greatest Canadian female third in history in a TSN poll of broadcasters, reporters and top curlers.

Joan McCusker, who had played second for both Schmirler and Betker retired from competitive curling and was replaced by her sister, Nancy Inglis.

Sherry Linton, former third, joined Jolene McIvor's rink for the 2006-2007 season and was replaced by newcomer, Lana Vey.
