Brigadier Simon Christopher Joseph Fraser, 15th Lord Lovat, was a prominent British Commando during the Second World War and the 24th Chief of the Clan Fraser of Lovat. Known familiarly as Shimi Lovat, an anglicised version of his name in Scottish Gaelic; his clan referred to him as MacShimidh, his Gaelic patronym. During Operation Overlord, he led the Special Service Brigade at Sword Beach and to successfully capture Pegasus Bridge, accompanied by his piper Bill Millin.

Clan Fraser of Lovat is a Highland Scottish clan and the principal branch of Clan Fraser. The Frasers of Lovat are strongly associated with Inverness and the surrounding area since the Clan's founder gained lands there in the 13th century.
