The Actes and Monuments, popularly known as Foxe's Book of Martyrs, is a work of Protestant history and martyrology by Protestant English historian John Foxe, first published in 1563 by John Day.

In Christianity, a martyr is a person who was killed for their testimony for Jesus or faith in Jesus. In years of the early church, stories depict this often occurring through death by sawing, stoning, crucifixion, burning at the stake, or other forms of torture and capital punishment. The word martyr comes from the Koine word μάρτυς, mártys, which means "witness" or "testimony".
