Dawn McEwen (born July 3, 1980 in Ottawa, Ontario as Dawn Askin) is a Canadian curler from Winnipeg, Manitoba. She currently plays lead for the Jennifer Jones rink. The team will represent Canada at the 2014 Winter Olympics.
McEwen grew up in Ottawa, where she began curling at the RCMP Curling Club at age seven. McEwen joined up with Jenn Hanna for the 2003–04 season playing as her second. In 2005, the team won the Ontario Scott Tournament of Hearts and lost in the final of the 2005 Scott Tournament of Hearts to Jennifer Jones.
In the 2006–07 season, McEwen was demoted to the team's alternate so she could focus on her career. In 2007, she moved to Winnipeg, and began playing for Jones. She won the Canada Cup with Jones in 2007. McEwen won her second provincial championship (first as a Manitoban) in 2008, and played in her second Tournament of Hearts with Jones, this time as teammate, winning in the finals against Alberta. She would later win the 2008 World Women's Curling Championship that year with Jones, beating China in the final.
McEwen together with the Jones team would reach the final again in the 2009 Scotties Tournament of Hearts, this time as returning champions, and sealed their victory as repeating Canadian champions with a win. They would go to the 2009 World Women's Curling Championship in Korea, but would suffer a defeat in the quarter-finals that put them out of the medal contention.
McEwen would continue as lead as the Jones team defended their title as Team Canada at the 2010 Scotties Tournament of Hearts. After tying for the lead in the round robin the team would play PEI and go straight to the final where they would have a rematch against PEI. After going down 6–3 the team would come from behind and win in extra ends, this was McEwen's third championship.
