The T8 Airport & South Line is a suburban rail service operated by Sydney Trains, connecting the Sydney central business district with the southwestern suburbs via Sydney Airport.

Since 2017 the line has been numbered T8 and is coloured green on maps and wayfinding information.

In March 2025, the federal minister for infrastructure, transport, regional development and local government Catherine King announced that a business case would be developed exploring a potential upgrade of the T8 Airport & South line.
