Sir Henry Calthorpe (1586–1637), was an English lawyer who acted as solicitor-general to Queen Henrietta Maria, and also as the defence barrister in two high-profile cases: the Darnell's Case (or the Five Knights' case) and the Valentine case. He was Recorder of London in 1635–36 (by king's mandate), attorney of court of wards in 1636, and was knighted the same year.
