Which actress played Claire Littleton in Lost?

Emilie de Ravin played Claire Littleton in Lost.

Claire is a pregnant Australian passenger who survives the crash of Oceanic Flight 815. Her pregnancy becomes an important part of the first season, especially as the survivors try to provide medical care and understand the island’s unusual effects.

De Ravin appeared as a main cast member during the early seasons and returned to the series after Claire’s disappearance from the beach camp. Her character’s relationships with Charlie Pace, Aaron, and the other survivors connect several major storylines.

The role helped establish de Ravin internationally after her earlier work in Roswell and other television productions. Claire is often confused with Kate Austen because both women are central female survivors, but Kate was played by Evangeline Lilly.
