Saint James Cavalier () is a 16th-century cavalier in Valletta, Malta, which was built by the Order of St John. It overlooks St James' Bastion, a large obtuse-angled bastion forming part of the Valletta Land Front. St James was one of nine planned cavaliers in the city, although eventually only two were built, the other one being the identical Saint John's Cavalier. It was designed by the Italian military engineer Francesco Laparelli, while its construction was overseen by his Maltese assistant Girolamo Cassar. St James Cavalier never saw use in any military conflict, but it played a role during the Rising of the Priests in 1775.
