Sir Samuel McClellan, MacClellan or McLellan (c. 1640–1709) was a Scottish cloth merchant and politician who sat in the House of Commons of Great Britain from 1708 to 1709.
[1] He was the eldest son of Rev Patrick McClellan (died 1666) of Girthon near Kirkcudbright and his wife Jean Primrose.
[2] MacClellan retained some interest during the 1670s in property in the stewartry (in 1676 he is recorded as owner of the Tannifad and Whinniehill farm estates) but he focused his attention on Edinburgh.
[2] In 1690 he received a lucrative contract for 647 military red coats from Alexander Gordon, Viscount Kenmure, replacing uniforms damaged in the Battle of Killiecrankie.
He was dean of guild in 1705 and in 1706 was elected Lord Provost of Edinburgh in succession to Sir Patrick Johnston at Michaelmas 1706.
McLellan was burgess of Perth in 1708, and at the 1708 British general election, was returned as Member of Parliament for Edinburgh.
He gave financial inducements to Robert Walpole and Sir David Dalrymple, 1st Baronet, to secure Scottish forage contracts.
He was succeeded by his eldest son, James, who subsequently made an abortive bid for the barony of Kirkcudbright, claiming to be the nearest male heir to a peerage that had failed in its main line.
