Dunedin Peninsula and Ocean Beach Railway was a railway line in Dunedin, South Island of New Zealand. The company was incorporated in 1874, and construction began in December 1875, and the 3.5 kilometres (2.2 mi) railway opened to Ocean Beach on 23 March 1876. Extensions were later opened to Anderson's Bay (in 1877), Forbury, Musselburgh and Tahora Bay. It closed in 1942, and part of it is now the Ocean Beach Railway, a heritage line.
