The 2005 Canada Cup was a women's rugby union competition held in Ottawa, Canada, between 29 June and 8 July 2005. It was the fourth Canada Cup tournament held, and the sixth when including the 2003 and 2004 women's Churchill Cup tournaments hosted by Canada. It was the first of the series in which the US did not compete — Canada's opponents were New Zealand and Scotland.
The competition returned to the 2003 format with a three-nation round-robin, followed by a final between the top two.
