Laurence Oliphant, 4th Lord Oliphant (1529–1593) was a Scottish nobleman.
The eldest son of Laurence Oliphant, 3rd Lord Oliphant, by Margaret Sandilands, in 1543 he was sent to England as a hostage for his father. After the marriage of Mary Queen of Scots to Darnley, while Master of Oliphant, he sat as an extraordinary member of the privy council in August 1565. In 1565 certain persons accused of serious crimes took over his house of Berrydale, which they garrisoned and held; but on 13 April 1566 they were ordered by the council to give it up to him within 24 hours under pain of being treated as rebels. He succeeded his father on 26 March of the same year, and was served heir on 2 May.
Oliphant sat on the assize for the trial of James Hepburn, 4th Earl of Bothwell for the murder of Darnley, signed the Ainslie Tavern Bond for Bothwell's marriage to the queen, and was one of the nine temporal lords present at the marriage. At the same time as John Hamilton he was admitted a member of the privy council. He joined the association on behalf of Mary at Hamilton on 8 May 1568, and fought for her at the battle of Langside. On this account he was charged to appear before the regent and lords of the privy council, and, failing to do so, was on 2 August 1568 denounced a rebel and put to the horn; but on 5 April 1569 he signed a "band for the king", and on 16 June again appeared as a member of the privy council.
Oliphant was one of sixteen persons appointed by Queen Mary, at Bolton Castle on 6 March 1569 to act as advisers, with the Duke of Châtellerault, the Earl of Huntly and Earl of Argyll, in the difficult circumstances of the Scottish kingdom. He attended the convention at Perth on 31 July of the same year, and voted against the queen's divorce from Bothwell. An attack on him and his servants on 18 July at the instance of George Sinclair, 4th Earl of Caithness was the subject of deliberation by the privy council on 12 October and 22 November.
