Rothsay is an abandoned town in the Mid West region of Western Australia.

The local progress association requested that a townsite be declared in 1897 and it was gazetted in 1898.

Later the town fell into decline but experienced a second lease of life when the entrepreneur Claude de Bernales reopened the mine in 1932.

Today the town is abandoned but remnants of the strong room, the mine manager's house and the derelict shaft are all that remain.

Both spellings were in currency in the town's early years, with Rothesay apparently used in the first instance.
