Clarisa Fernández (born 28 August 1981) is an Argentine former professional tennis player.

She is best known for her semifinal appearance at the 2002 French Open, the first Argentine since Sabatini in 1992 to reach that stage.

She defeated, in order, Lubomira Bacheva, Jelena Kostanić, Kim Clijsters (No.

In April 2008, Fernández announced her retirement from professional tennis after a lengthy battle with knee injuries.
