The Carlingford railway line was a railway line in Sydney, Australia. It was opened from Clyde to Subiaco (later renamed Camellia) in January 1885, then by means of the construction of a bridge across the Parramatta River, to Carlingford in April 1896. It closed on 5 January 2020 with much of the line to be converted to light rail as part of the Parramatta Light Rail network, while a short section of the line was retained for use by Sydney Trains.
