Ghislaine Elizabeth Marie Thérèse Perreau-Saussine (born February 6, 1941), known professionally as Gigi Perreau, is an American film and television actress.

[1] Her elder brother Gerald (stage name Peter Miles) and, to a lesser extent, her younger sisters Janine and Lauren, also had a measure of success in film and on television.

[3] The two-year-old, who could speak French, got the (uncredited) part of Madame Curie's daughter Ève (while Gerald would have to wait a year to make his film debut in Passage to Marseille).

As the "top child movie actress for 1951", the then ten-year-old was given the keys to the city of Pittsburgh by its mayor, and later Pennsylvania governor, David L. Lawrence.

Also in 1960, Perreau was cast as Julie Staunton in the episode "Flight from Terror" of the ABC adventure series The Islanders, set in the South Pacific.

She was cast in a recurring role on ABC's Follow the Sun series from 1961–1962 as a secretary, Katherine Ann "Kathy" Richards.

As of 2010, she was a member of the board of directors of both the Donna Reed Foundation for the Performing Arts and the Will Geer Theatricum Botanicum and is the vice-president of the Drama Teachers Association of Southern California.
