Harry Rutherford Jackman (November 5, 1900-November 22, 1979) was a Canadian politician and successful entrepreneur. He represented the electoral district of Rosedale in the Canadian House of Commons from 1940 to 1949.

He was first elected in 1940 as a member of Robert Manion's World War II National Government caucus (which, despite the name, formed the Official Opposition in the Canadian House of Commons), and was reelected in 1945 as a Progressive Conservative. He ran again in 1949, but was defeated.

In business, Jackman built the Empire Life group of financial service companies during the Great Depression.

Jackman married Mary Coyne Rowell, the daughter of Canadian politician Newton Wesley Rowell, in 1930. They had four children: Henry (Hal), Eric, Edward and Nancy.
