Sir Robert Lauder of Popill (died April 1575) was a Scottish landowner and an adherent of Mary, Queen of Scots.
Robert Lauder was bound by the marriage contract dated 12 August 1556, under penalty of £4000 Scots, to complete the bond of matrimony "in the face of The Holy Church" before Michaelmas next thereafter.
However, he failed to do so, and an Inhibition to the recording of the contract, was registered 12 September 1556, and accordingly the Mistress of Bothwell brought an action for the amount of forfeit, which was heard on 20 December 1558.
On 17 March 1566, Robert Lauder younger of the Bass, was appointed Captain of Tantallon Castle, the Keeper being the Earl of Atholl.
[3] Robert Lauder had a remission, with other members of his family, from Regent Moray for fighting on the Queen's side at the battle of Langside in 1568.
