Alexandra Lamy (born 14 October 1971) is a French actress.

Lamy was born in Villecresnes, near Paris, but grew up in Languedoc-Roussillon. When she was six months old, her parents, Michel and Michèle, moved the family to La Grande-Motte in Southern France. A few years later, her family moved again to Alès, where her father ran a fabric shop. She fell in love with theatre while performing in school plays. She later moved to Paris to begin her career, where she worked to lose her southern French accent.
