Harry Wright Wallace (11 September 1885 – 30 April 1973) was a British Labour Party politician.
He was Assistant Secretary of the Post Office Workers Union.
At the 1924 general election, he was unsuccessful Labour candidate at Bury in Lancashire.
At the 1929 general election, he was elected as Member of Parliament (MP) for Walthamstow East. He lost the seat two years later, as Labour's vote collapsed in the 1931 election when party split over its leader Ramsay Macdonald's formation of a National Government.
Wallace regained his seat in the Labour landslide at the 1945 general election, and held the seat until his defeat at the 1955 general election by the Conservative John Harvey.
