Sir Christopher Calthorpe KB (c. 1645 – 7 February 1718) was an English Member of Parliament.
[1] Calthorpe was born into a rich Norfolk family which had held manorial property in East Anglia since 1376 and had first represented the county in Parliament under Henry VI.
His father was a Parliamentary sympathiser in the Civil War and had held local office under the Commonwealth.
In 1688, Calthorpe bluntly declared that he could not give his assent to the repeal of the Test Act and Penal Laws, and he was removed from local office as a Justice of the Peace.
A non-juror after the Glorious Revolution, he was disarmed in September 1689 at the behest of his rival, Sir Henry Hobart, and in the following summer he was placed in confinement as a person ‘suspected to be dangerous to the peace of the kingdom’.
