Franklin White Turnbull (19 June 1881 – 24 February 1971) was a Conservative member of the House of Commons of Canada. He was born in Carleton County, Ontario and became a barrister.

Turnbull attended schools at Vankleek Hill, Ontario, Edmonton, and Springhill, Ontario (secondary school number 8). He studied law with F.W.A.G. Haultain in Regina, Saskatchewan.^[1]

He was first elected to Parliament at the Regina riding in the 1930 general election after a previous unsuccessful campaign there in the 1925 election. Riding changes meant that Turnbull became a candidate at the new Regina City riding for the 1935 election, but was defeated by Donald McNiven of the Liberal party.
