Sir Nathaniel Barnardiston (1588 – 25 July 1653) was an English politician who sat in the House of Commons variously between 1628 and 1648.

In 1628 Barnardiston was elected Member of Parliament for Suffolk and held the seat until 1629 when King Charles decided to rule without parliament for eleven years. In April 1640, he was re-elected MP for Suffolk in the Short Parliament and again in November 1640 for the Long Parliament. He is not recorded as sitting after Pride's Purge in 1648.

Barnardiston died at the age of 65.

Barnardiston married Jane Soame daughter of SIr Peter Soame, Lord Mayor of London. Their sons Thomas and Samuel both became MPs and baronets.
