Andrew Crosbie of Holm FRSE FSA(Scot) (1736-1785) was a Scottish lawyer and antiquarian, and a notable figure of the Scottish Enlightenment. He was a close friend and companion of James Boswell and co-wrote the legal song The Justiciary Opera, sung by generations of Scottish advocates, with him.
He was born in the Soutergate, Dumfries, the only surviving son of Andrew Crosbie of Holm (d.1762), the provost of Dumfries, and his wife, Jean Grierson. His early education was at Dumfries Academy.
He studied Law at the University of Edinburgh, and was admitted to the Faculty of Advocates in 1757.
In 1769, together with James Boswell, he helped to fund the Corsican rebels fighting under Pasquale Paoli.
Around 1770 he began building his own house on St Andrews Square at the east end of the then first phase of Edinburgh's New Town. However he was financially ruined in 1772 by the demise of Douglas, Heron & Co, a bank in Ayr in which he was a partner.
As a member of the Edinburgh Philosophical Society when it was awarded a royal charter in 1783, he automatically became a founding Fellow of the Royal Society of Edinburgh.
An office-bearer ('Assassin') of The Poker Club, and a friend of Boswell and Johnson, Crosbie was the basis of the character Councillor Pleydell in Sir Walter Scotts's novel Guy Mannering.
