Mo Mowlam, English academic and politician, Chancellor of the Duchy of Lancaster (b. 1949)
Marjorie "Mo" Mowlam (18 September 1949 – 19 August 2005) was a British Labour Party politician. She was the Member of Parliament (MP) for Redcar from 1987 to 2001 and served in the Cabinet as Secretary of State for Northern Ireland, Minister for the Cabinet Office and Chancellor of the Duchy of Lancaster.

Mowlam's time as Northern Ireland Secretary saw the signing of the historic Good Friday Peace Agreement in 1998. Her personal charisma and reputation for plain speaking led her to be perceived by many as one of the most popular "New Labour" politicians in the UK. When Tony Blair mentioned her in his speech at the 1998 Labour Party Conference, she received a standing ovation.
