Henry Abbot (died 4 July 1597) was an English layman, himself a convert from the Church of England, who was executed at York for the alleged attempt to convert someone to the Catholic Church, which had been declared an act of treason under the Penal Laws enacted under Queen Elizabeth I.
He is considered a martyr for the faith by the Catholic Church, which has beatified him.
Abbot was reprieved till the next July, when he was executed alongside William Andleby, Thomas Warcop, and Edward Fulthrop.
The first three were beatified on 22 November 1987 by Pope John Paul II.
Abbot was declared Venerable on 8 December 1929, and was beatified on 15 December 1929 by Pope Pius XI as part of a group of 137 citizens of England and Wales who met that same fate.
