The Tangara (an Aboriginal Australian word meaning to go) is a class of electric multiple unit operated by Sydney Trains in Sydney, Australia. The Tangaras were delivered between 1988 and 1995, and are third-generation trains.

A Tangara is a double-deck four-car set, with the two outer cars being driving control trailers fitted with one pantograph each and the middle two cars being non-control motor cars. They are equipped with air conditioning and chopper control.

Two subclasses of Tangara were built, the suburban sets targeted as T sets, and outer-suburban sets targeted as G sets. The T sets replaced the first generation of Sydney's electric rolling stock.

Unlike most other Sydney Trains trains the seats on the T sets are fixed, meaning that half the seats face backwards.

The G sets differed from the T sets in having yellow front panels, round green door buttons, high-backed reversible seats, toilets, fresh water dispensers and luggage racks.

Set G7 was fitted with an AC drive system for evaluation purposes with the existing DC stock and compatibility with signalling and communication systems on the network. G7 was scrapped in 2005 at Maintrain, Auburn after the Waterfall train disaster, as all four cars were beyond repair.

In July 1986 the Government of New South Wales awarded A Goninan & Co a contract for 450 carriages. In 1993 it was decided that the last 80 carriages of the order would be built to a modified design to operate peak-hour services on services to Wyong, Port Kembla and Dapto. In 1996 five spare driving trailers were ordered.

The first train was unveiled at Sydney Central in December 1987, entering service in April 1988. The final T set was delivered in February 1994 and the final G set in October 1995.
