Sir Robert Throckmorton of Coughton Court, Warwickshire, MP, KG (c. 1513 – 12 February 1581) was a distinguished English Tudor courtier. His public career was impeded by being a Roman Catholic.
Born by 1513, Robert Throckmorton was the eldest son and heir of Sir George Throckmorton (d.1552) by Katherine Vaux, daughter of Nicholas Vaux, 1st Baron Vaux of Harrowden (d.1523). He had several brothers, the most notable being, in descending seniority: Sir Kenelm Throckmorton, Sir Clement Throckmorton MP, Sir Nicholas Throckmorton (1515-1571), Thomas, Sir John Throckmorton (1524-1580), Anthony and George.
Robert Throckmorton may have trained at the Middle Temple, the inn attended by his father. At least three of his younger brothers and his own eldest son studied at Middle Temple, but as the heir to extensive estates he had little need to seek a career at court or in government. He was joined with his father in several stewardships from 1527 and was perhaps the servant of Robert Tyrwhitt, a distant relative by marriage of the Throckmortons, who in 1540 took an inventory of Cromwell's goods at Mortlake. He attended the reception of Anne of Cleves and with several of his brothers served in the French war of 1544. Three years later he was placed on the Warwickshire bench and in 1553 was appointed High Sheriff of Warwickshire. He was also elected as a knight of the shire (MP) for Warwickshire in 1553 and 1555. Three of his brothers also sat for Parliament, Nicholas as knight of the shire for Northamptonshire.
