Sir John Napier, 4th Baronet (1636–1711) was an English landowner and politician who sat in the House of Commons between 1664 and 1679.
Napier was the son of Sir Robert Napier, 2nd Baronet and his second wife Penelope Egerton, daughter of John Egerton, 1st Earl of Bridgwater and was baptised at Luton Hoo on 5 July 1636.
He also inherited the re-patented Napier baronetcy since his father had surrendered the original patent when disinheriting the family of his first wife.
