Croydon South was a constituency represented in the House of Commons of the Parliament of the United Kingdom. It elected one Member of Parliament (MP) by the first past the post system.

It was created for the 1918 general election when the County Borough of Croydon had grown so the Croydon seat was split into two seats.

In 1974 the seat was redrawn and renamed Croydon Central; following the 1965 addition of Purley and Coulsdon to the London Borough of Croydon in 1974 a fresh seat of Croydon South was created to the south predominantly from East Surrey rather than from the historic Croydon South.

It did not exist from 1950 to 1955 as an east–west division of the town was chosen instead. Its voters elected twice Labour candidates, for the 1945 and 1966 Parliaments when the Labour Party received strong majorities, and at all other elections elected Conservative candidates.
