HMS Portisham was one of 93 ships of the Ham-class of inshore minesweepers.

Their names were all chosen from villages ending in -ham. The minesweeper was named after Portesham in Dorset, using an alternative spelling for the village.

After her sale in 1989 she was laid up and for sale in a boatyard in Essex. She was procured for conversion to a liveaboard ship by an Irish national in 2007 and is currently the second biggest private vessel under the Irish flag.
