John Barton (15th century) was an English writer on Lollardy.
Barton appears to have flourished in the reign of Henry V, to whom he dedicated his 'Confutatio Lollardorum.'
A manuscript copy of this work is preserved in the library of All Souls' College, Oxford, written in a hand which Henry Octavius Coxe assigned to the 15th century.
Other manuscripts of this author are mentioned by Thomas Tanner, who wanted to identify him with a certain John Barton, Esq., buried in St. Martin's Church, Ludgate, 1439.
Tanner says that he was possibly chancellor of Oxford; but he fails to give any authority.
