Donald Matheson Sutherland, PC (December 3, 1879 – June 4, 1970) was a Canadian physician and politician.

He ran for public office, as a Laurier Liberal, in the 1917 federal election held as a result of the Conscription Crisis of 1917, but was defeated in the riding of Oxford North.

By 1921, he had changed allegiances to the Conservatives and, in the 1925 general election, won the seat of Oxford North and became a Tory Member of Parliament in the House of Commons of Canada.

He was defeated, however, in the 1926 general election which returned the Liberals under William Lyon Mackenzie King to power following the King-Byng Affair.

In 1934, with the country reeling from the Great Depression, Bennett, as prime minister, instituted his own version of Franklin D. Roosevelt's New Deal.
