Charles Mapp (1903 – 3 May 1978) was a British Labour Party politician.
From a working-class background, Mapp won a scholarship to a grammar school.
He worked as a railway goods agent, and was elected to Sale Borough Council in 1932 (serving until 1935) and 1945 (retiring the following year).
He was reselected for Oldham East and won the seat in the 1959 general election, against the national tide because of depression in the local textiles industry.
Mapp also worked as a juvenile court magistrate.
