John Murphy (c. 1753 – c. 2 July 1798) was an Irish Roman Catholic priest of the Roman Catholic Diocese of Ferns, who is mainly remembered for his central role in the Irish Rebellion of 1798 in County Wexford, which is sometimes known as the Wexford Rebellion. He led the rebels to one of their initial victories over a government militia at Oulart Hill, and in the following weeks became one of the rebellion's main leaders. Following the suppression of the rebellion Murphy was taken in early July near Tullow and summarily executed.
