Jane Wanjiku Gakunyi (born 14 June 1979) is a Kenyan long-distance runner.

At the 2003 World Cross Country Championships she finished third in the short race, while the Kenyan team, of which Wanjiku was a part, won the team competition. She finished ninth at the 2004 World Cross Country Championships, but this was not enough to win a medal with the team.

She is not to be confused with Jane Wanjiku Ngotho, a Kenyan runner and world junior champion from 1988.
