Rachel Elise Blanchard (born 19 March 1976 in Toronto, Canada) is a Canadian actress. Her career was launched with a part in a McDonald's commercial. Blanchard is probably best known for playing the part of Cher Horowitz (originally portrayed by Alicia Silverstone) on the TV version of the 1995 movie Clueless. Her looks are similar to those of other blonde actresses with whom she might be confused, Maggie Lawson and Sara Paxton.

The brave step of performing in a British sitcom paid off in 2004, when she received critical acclaim for her performance in the award-winning second series of Peep Show.
