MV Lochearn was a mail steamer operated by David MacBrayne from Oban to Barra and South Uist from 1930 until 1955.

She then became the Sound of Mull mail steamer until 1964, when she was superseded by a new generation of car ferry and sold for further service in the Greek Islands.

[2] In March 1931 in thick fog, Lochearn ran aground on a sandbank at Lonbane, Applecross.

[3] With the introduction of the 1964 hoist-loading car ferries, Hebrides, Clansman and Columba, Lochearn became redundant.

[11] Based in Oban, Lochearn was the Inner Isles mail steamer, serving Tobermory, Coll, Tiree, Barra and South Uist[4] until 1955 when she was replaced by MV Claymore.
