Robert Shapcote (born 1621, died 1689) was an English lawyer from Devon and four times Member of Parliament for Tiverton in 1646–1649, 1654, 1656 and 1660. He sat in the Irish House of Commons for Wicklow Borough from 1661 to 1665 and was briefly Attorney-General for Ireland. He fought in the Parliamentary army in the Civil War.
Shapcote was the eldest son of Henry Shapcote of Bradninch and his first wife Wilmot Hill, and was baptised on 4 February 1621. He entered Lincoln's Inn in 1638 and was called to the bar in 1645. From 1644 to 1646, he was a colonel in the Parliamentary army. He was elected Member of Parliament for Tiverton for the Long Parliament on 7 December 1646 but was excluded in 1649 under Pride's Purge.
Shapcote became Recorder of Tiverton by 1647 and was also recorder of Bradninch and South Molton. He was J.P. for Devon from 1647 to 1649. In 1654 he was elected MP for Tiverton in the First Protectorate Parliament. He became commissioner for militia for Devon and commissioner for oyer and terminer on Western circuit in 1655. In 1656 he was re-elected MP for Tiverton for the Second Protectorate Parliament. Also in 1656 he became commissioner for security, commissioner for assessment for Devon, commissioner for fraudulent debentures and Solicitor-General for Ireland. He became commissioner for new buildings in London in 1657. In 1659 he was unsuccessful in his attempt to be re-elected MP for Tiverton in a double return. He was deprived of his position as Solicitor General for Ireland when the Rump Parliament was restored, but became Attorney-General for Ireland when the secluded members were allowed in. In April 1660 he was elected MP for Tiverton again for the Convention Parliament in which he was very active, being particularly concerned with Irish matters, and with the religious settlement. He opposed the unconditional restoration of the Church of England hierarchy. remarking that "I am not against the Bishops, but their power".
In 1661 Shapcote went back to Ireland to practice law. A tentative offer of a renewal of Government employment was politely refused. He stood for three constituencies in the 1661 Irish parliament, and was elected for Wicklow Borough. He was highly regarded by the Cromwellians in Ireland, whereas Royalists denounced him as "a great fanatic" and the leader of "the seditious faction". There is no doubt that he had a following in the Commons, although the extent of his influence has been disputed. Captain Blood consulted him on the plan to attack Dublin Castle in 1663, which Shapcote discouraged. However Shapcote was arrested, and it was proposed to try him for treason as an example. The Law Officers advised that it would be very difficult to secure a conviction, and it was decided to simply leave him in prison for the time being. After a year's imprisonment, on the intercession of Sir Courtenay Pole, 2nd Baronet, who had married his cousin, he was pardoned and released, but was expelled from the Irish parliament. He continued with his legal practice in Ireland, but took no further part in politics.
On 15 May 1646 Shapcote married Anne Walrond, a daughter of Henry II Walrond (1584–1650) of Bradfield House, Uffculme, Devon He had a son who apparently died young and a daughter Urith, who married her cousin Francis but had no children.
Shapcote died before 3 May 1689, but the exact date is unknown.
