Celia, Viscountess Whitelaw (1 January 1917 – 5 December 2011) was the wife of William "Willie" Whitelaw, MP, former Home Secretary, Deputy Prime Minister and aide to Margaret Thatcher.

She was referenced in the book, Debs at War 1939-1945: How Wartime Changed Their Lives, written by Anne de Courcy.

After her husband returned to civilian life following World War II, she played an active role in helping him run his family estates in Dunbartonshire and Lanarkshire. When he decided to go into politics in the 1950s, she became first a vivacious campaigner and later an active parliamentary wife.
