Colonel Alexander Perceval (1787 – 9 December 1858) was an Irish politician.
He sat in the House of Commons for Sligo County from 1831 to 1841, when his growing financial difficulties compelled him to resign his seat. He served briefly as a Junior Lord of the Treasury in Sir Robert Peel's second government (1841). He was Sergeant-at-arms of the House of Lords from 1841 until his death. 
He died at Chester Street, London, on 9 December 1858 and was buried at West Norwood Cemetery. He had married Jane Anne, the daughter of Col. Henry Peisley L’Estrange of Moystown, Cloghan, King’s County and had a large family. Due to his extravagance Temple House had to be sold but was bought back for the family by his third son, also Alexander (1821-1866).
