Sheila Gish (23 April 1942 – 9 March 2005) was a British stage and television actress. She was born Sheila Anne Gash in Lincoln, studied at the Royal Academy of Dramatic Art, and made her stage debut with a repertory company.

Her first starring role in the West End was as Bella in Robert and Elizabeth. She continued to be best known for her stage work, but she also appeared in many television dramas, from The First Churchills (in which she played Mary of Modena) to the successful adaptation of Love in a Cold Climate (2001) in which she played the eccentric and outrageous Lady Montdore. She had two daughters: the actresses Kay Curram and Lou Gish (1967–2006) by her first husband, the actor Roland Curram.
