George Perry Graham, PC (March 31, 1859 – January 1, 1943) was a journalist, editor and politician in Ontario, Canada.

When Ross resigned as leader of the Ontario Liberal Party in 1907, Graham briefly succeeded him, but quickly left later that year for federal politics when he was appointed Minister of Railway and Canals in the Liberal government of Prime Minister Sir Wilfrid Laurier.

Ross won the Brockville seat in the House of Commons of Canada in a by-election in 1907.

He was defeated in the 1911 federal election that brought Robert Borden's Conservatives to power, but returned to the House of Commons in a 1912 by-election.

He lost his seat in the 1925 federal election, but was appointed to the Senate of Canada in 1926, and sat in that body until his death in 1943.
