Cronulla railway station is the heritage-listed terminus railway station on the Cronulla line in Cronulla in the Sutherland Shire local government area of New South Wales, Australia. It was designed and built by the NSW Department of Railways during 1939. It is also known as Cronulla Railway Station group. The property was added to the New South Wales State Heritage Register on 2 April 1999. The station serves the Sydney suburb of Cronulla via Sydney Trains' T4 line services. The station is unusual in that the two platforms are situated end to end, rather than side by side, making it the second longest rail platform in New South Wales, after Albury.

In 1908, the NSW Government had approved construction of a steam tram route from Sutherland to Cronulla, with construction completed and steam trams operating along the route from 12 June 1911. The area remained mostly semi rural in the inter-war period. After World War II there was a large population increase and the area was suburbanised from the 1950s, with many of the guest houses being replaced by high rise flats. The Sutherland-Cronulla line was constructed from 1936 and completed in 1939, under the NSW premiership of the conservative Sir Bertram Stevens. In 1936 the NSW Parliament authorised expenditure of A£300,000 to construct the Sutherland to Cronulla railway line, with the men employed to receive award wages "in pursuance of the Cabinet's policy of replacing unemployment relief works by works that will provide a better return for the expenditure of public money, and at the
