Roger Hill (1 December 1605 – 21 April 1667), of Poundisford Park in Somerset, was an English judge and Member of Parliament.
In March 1644, he was the junior of the five counsel employed against Archbishop Laud, and from 1646 headed a set of Chambers in the Temple.
Though named in the commission for the trial of the King he never sat on it, but he subsequently served as assistant to the attorney-general during the Commonwealth.
In that capacity, he assisted at the ceremony of investiture of the Lord Protector in June 1657; and as one of the judges attendant on Cromwell's House of Peers, he delivered a message from them to the Commons in the following January.
In the summer of 1658 he went on the Oxford circuit with Chief Justice Glynne, an account of the proceedings of which, "writ in drolling verse", was published soon afterwards.
