Sir Nicholas Slanning (1 September 1606 - August 1643) was a soldier and landowner from Devon who sat in the House of Commons from 1640 to 1642. He served in the Royalist army during the First English Civil War and was mortally wounded at Bristol on 26 July 1643.

A member of a wealthy family with extensive estates in Devon and Cornwall, Slanning gained military experience in the Thirty Years' War and was appointed Vice Admiral of South Cornwall and Governor of Pendennis Castle in 1635. He served in the 1639 and 1640 Bishops' Wars and was elected MP for Penryn in the Long Parliament, where he consistently supported Charles I.

Following the outbreak of the Civil War in August 1642, he raised a regiment of infantry from his estates in Cornwall and played a prominent role in the 1643 Western campaign, which ensured Royalist control of South West England. Badly wounded in assaulting Bristol on 26 July, he died three weeks later.
