George Forbes Dewar (December 12, 1865 – November 25, 1961)[1] was a physician and political figure in Prince Edward Island, Canada.
He represented 3rd Queens in the Legislative Assembly of Prince Edward Island from 1911 to 1915 as a Conservative member.
Dewar obtained a teacher's licence from Prince of Wales College and then went on to study medicine at McGill University, receiving an M.D.
Dewar was elected in a 1911 by-election held after Herbert James Palmer was named premier and so was required to run for reelection.
As a result of Palmer's defeat, the Liberals lost their majority in the assembly and a new general election was held later that year.
