John Eyton (c. 1591 – March 1661) was a Welsh politician who sat in the House of Commons in 1614.
He possibly matriculated from Hart Hall, Oxford on 12 November 1607 and entered Lincoln's Inn in 1609.
In 1614, he was elected Member of Parliament for Flint.
Eyton married Susan, the daughter of Thomas Puleston of Lightwood, Overton, Flintshire and had at least three sons (two of whom predeceased him) and four daughters.
