HMIS Indus was a Grimsby-class sloop of the Royal Indian Navy launched in 1934 and sunk during the Second World War in 1942.

She was a slightly enlarged version of other vessels in the Grimsby class.

In March 1942, British Indian Army and British Army troops from Rangoon had to be withdrawn, as they were overwhelmed by the superior numbers as well as the air command of the Japanese.

The Flag-Officer-Commanding of the Eastern Fleet refused to withdraw Indus and Sutlej from the anti-infiltration patrol off Akyab.

On 6 April, Indus suffered 3 direct bomb hits in an air raid by Japanese Mitsubishi G3M bombers, and sank in 35 minutes.
