Bass Coast is part of the Gippsland region in southeastern Victoria, Australia. It includes Phillip Island and the region of the mainland through which the Bass Highway passes. It has a long coastline on Western Port Bay and the open seas of Bass Strait. Its landward side is enclosed by South Gippsland.
The Bass Highway turns off the South Gippsland Highway and runs down the eastern side of Western Port Bay, past the turn-off to San Remo and Phillip Island, then runs along the Bass Strait coast to Inverloch before turning inland to rejoin the South Gippsland Highway at Leongatha.
