César Award for Best Female Revelation

The César Award for Best Female Revelation (French: César de la meilleure révélation féminine) is one of the César Awards, presented annually by the Académie des Arts et Techniques du Cinéma to recognize the outstanding breakthrough performance of a young actress who has worked within the French film industry during the year preceding the ceremony. Nominees and winner are selected via a run-off voting by all the members of the Académie, within a group of 16 actresses previously shortlisted by the Révélations Committee.

It was presented as the César du meilleur jeune espoir féminin from 1983 to 2004 and the César du meilleur espoir féminin from 2005 to 2023. In English, the award was variously referred to as Most Promising Actress or Best Female Newcomer.
