RMS Orizaba was a Royal Mail Ship wrecked off Rockingham, Western Australia on 16 February 1905.

On her approach to Fremantle, a smog of bushfire smoke was obscuring the coast and the captain lost his bearings.

The ship went aground in 6.1 metres (20 ft) of water on Five Fathom Bank, west of Garden Island.

It is one of the largest ships ever to be wrecked in Australian waters.

[4] The ship was celebrated in music by Australian composer Auguste Wiegand, in his gavotte of the same name.
