Alexander Briant was a 16th-century English Jesuit priest who was martyred at Tyburn. Born in Somerset in 1556, he pursued his education at Oxford, attending Hart Hall and later converting at Balliol College. Following his ordination in March 1578, he joined the English mission in August 1579. After his arrest in April 1581, he endured torture in the Tower of London and entered the Society of Jesus while imprisoned. He was convicted of high treason and executed in December 1581 at the age of twenty-five.
