Sir Robert King, 1st Baronet PC (circa 1625 – March 1707) was an Anglo-Irish politician.
King was the son of Sir Robert King and Frances Folliott. He represented the seat of Ballyshannon in the Irish House of Commons between 1661 and 1666. On 27 September 1682 he was created a Baronet, of Boyle Abbet, in the Baronetage of Ireland. He sat for Roscommon County from 1692 to 1693 and again from 1696 to 1699. In 1695 he was made a member of the Privy Council of Ireland. He finally sat for Boyle between 1703 and his death in 1707.
He married Frances Gore, daughter of Lt-Col Henry Gore and Mary Blayney. He was succeeded by his eldest son, John King. A descendant of his second son, Henry King, was created Earl of Kingston in 1768. 
Sir Robert was Charles II’s Muster-Master-General of Ireland. 
This is probably the Sir Robert King that Thomas Bellingham records in his diary meeting in Liverpool on 3 October 1688.
