Sir John Lauder of Fountainhall, 2nd Baronet, Lord Fountainhall (baptised 2 August 1646 – 20 September 1722) was one of Scotland's leading jurists who remains to this day an oft consulted authority. He was knighted in 1680 and matriculated his Arms with the Lyon Court on 15 June 1699. He gives his name to Fountainhall Close on the Royal Mile in Edinburgh, it being the location of his Edinburgh townhouse.
