Jennifer Ann Hanna (born January 22, 1980[1]) is a Canadian curler from Nepean, Ontario.

[3] Hanna competed at the 1998 Canadian Juniors, losing in the final to New Brunswick's Melissa McClure.

She was invited by Sherry Middaugh, the 2004 Ontario champion, to be the team's "fifth player" at the 2004 Scott Tournament of Hearts.

[7] In the 2005 Ontario Women's Curling Championships, Hanna and her team, consisting of Pascale Letendre, Dawn Askin and her sister Stephanie Hanna, recovered from a 1-4 record in the round-robin to win eight straight games and clinch the Championships, earning the right to represent Ontario at the 2005 Scott Tournament of Hearts in St. John's, Newfoundland and Labrador.

[8] At the 2005 Scotts, she caught the attention of many by winning the Ford Hot Shots competition and defeating defending champion Colleen Jones in the first draw.

[10] Hanna would end up winning both of her tie-breakers, against Cathy King of Alberta and Sandy Comeau of New Brunswick, allowing her to make the playoffs.

[11] She then proceeded to defeat Stefanie Lawton of Saskatchewan in the 3 vs. 4 game, followed by Kelly Scott of British Columbia in the semi-final, to face the Jennifer Jones rink from Manitoba in the final.

[citation needed] The new Hanna team started the 2005-06 season well, with their first ever Women's Tour victory, winning the Autumn Gold Classic in Calgary, Alberta on October 17, 2005.

At the Ontario Scott Tournament of Hearts, however, Hanna's team lost in the quarter-final to two-time World Champion Marilyn Bodogh.

The team, which was bounced from Regions, came through by winning the last chance Challenge Round, qualifying them for the 2009 Ontario Scotties Tournament of Hearts.

At the 2009 Ontario Scotties, the team finished the round robin with a 5-4 record, and lost in their tie-breaker match to Alison Goring.

On March 7, 2016, Hanna again announced she would be stepping back from the game, citing a desire to focus on her work and family.
