Sir Henry Lumley Drayton PC KC (April 27, 1869 – August 28, 1950) was a Canadian lawyer and politician.

Born in Kingston, Ontario, the son of Philip Henry Drayton, who came to Canada with the 16th Rifles of England, and Margaret S. Covernton, Drayton was educated in schools in both England and Canada. He was called to the Ontario Bar in 1891 and was created a King's Counsel in 1908.

From 1893 to 1900, Drayton was an Assistant City Solicitor for Toronto. In 1900, he formed a partnership with Charles J. Holman. In 1902, he was appointed Counsel to the Railway Committee of the Ontario Legislature. From 1904 to 1909, he was a County Crown Attorney for the County of York. In 1910, he was appointed Counsel for the Corporation of the City of Toronto. In 1911, he was appointed to the Toronto Power Commission. In 1912, he was appointed Chief Commissioner of the Board of Railway Commissioners for Canada.

Drayton was first elected to the House of Commons of Canada from Kingston in a 1919 by-election as a Conservative Party candidate. He served as Minister of Finance under both Sir Robert Borden and Arthur Meighen until the Conservative Party's defeat in the 1921 general election. Drayton kept his seat in that election.

In 1927, he was a candidate the leadership of the Conservative Party, but finished in last place. Drayton retired from politics in 1928 to become chairman of the Liquor Control Board of Ontario.

He attempted to return to Parliament in the 1945 election from a seat in Victoria, British Columbia, but lost narrowly to the Liberal candidate.

He was conferred a knighthood as a Knight Bachelor, which carries no postnominal letters, but carried the title 'Sir' before his name though.

Drayton married Edith Mary Cawthra and had three daughters. He died on 28 August 1950, at the age of 81.
