Cæsar Clement (died 28 August 1626) was an English Catholic recusant.
Shortly thereafter, Clement was sent to the English College, Rome, where he was admitted 5 September 1579.
Though originally destined for the English mission, Clement never went to England, but held the major positions of Dean of St. Gudule's, Brussels, and Vicar general of the King of Spain's army in Flanders.
He was a generous benefactor to English Catholic exiles, especially the Augustinian Canonesses of Louvain.
In 1612 he, along with Robert Chambers, was commissioned from Rome to make a visit to Douai College so as to put an end to the dissatisfaction with the administration there.
