Elisabeth Pepys (Elisabeth de St. Michel) (1640–1669) was the wife of Samuel Pepys, whom she married in 1655, shortly before her fifteenth birthday.

Her father, Alexandre de St. Michel, was born a French Catholic but converted to the Protestant faith. He married Dorothea, the daughter of Sir Francis Kingsmill, in Ireland. Elisabeth was born at or around Bideford on 23 October 1640. She died of typhoid on 10 November 1669.

Elisabeth was second cousin once removed to the writer Anne Kingsmill Finch.
