HMS Thetis was a Briton-class wooden screw corvette built for the Royal Navy in the late 1860s.

Thetis was driven ashore in 1874 whilst on duty in the East Indies.

It was reported that she would be repaired at Bombay, India or Trincomalee, Ceylon.

[2] The fire was caused by improper storage of materials on board which spontaneously combusted.

[3] She was present at the Bay of Pisagua when Chilean troops captured the port on 2 November 1879, during the Tarapaca Campaign.
