Who Do You Think You Are? is a Canadian television documentary series, which aired on CBC Television during the 2007-2008 television season. It was on Thursday evenings at 7:30 p.m. starting October 11, 2007. Based on the earlier BBC series Who Do You Think You Are?, each episode profiled a Canadian celebrity tracing their family tree. The series was announced in June 2007 as part of the CBC's schedule for the 2007–2008 season. In April 2008 it was announced that the CBC had cancelled the show.

Celebrities profiled included Don Cherry, Chantal Kreviazuk, Shaun Majumder, Sonja Smits, Randy Bachman, Mary Walsh, Margot Kidder, Lewis MacKenzie, Steven Page, Avi Lewis, Margaret Trudeau, Scott Thompson and Measha Brueggergosman.

After a four-year absence, the show was rebroadcast during the 2012–13 season with guest host Jeff Douglas. However, only 7 of the original 13 episodes were rebroadcast: Cherry, Kreviazuk, Page, Bachman, Trudeau, Majumder, and Bruegergosman.
