Sarah Hallam Douglass (d. Philadelphia, 1773)[1] was an English-born American stage actress and theatre director.

[2] She was an actor married to Lewis Hallam, with whom she travelled to America to perform in his company in May 1752 on board the Charming Sally.

[5] Sarah Hallam, along with the other female members of the troupe, was thus among the first professional leading lady in North America.

She performed principal female roles until she gradually left them to Margaret Cheer and Nancy Hallam in the mid-1760s.

[1][6] After the death of Lewis Hallam she married David Douglass,[1][6] with whom she formed the American Company in 1758.
