The Windsor Martyrs were English Protestants martyred at Windsor in 1543. Their names were Robert Testwood, Anthony Pearson and Henry Filmer. In 1543, during the reign of Henry VIII, the three Windsor Martyrs were arrested by Bishop Gardiner's agent, Dr John London, on the evidence of , the Catholic former Mayor of Windsor, who had a grudge against them. John Marbeck and Robert Benet were also arrested, but were later released. The three were condemned on 26 July, after Simonds threatened the jurors, and burnt to death on 4 August on the site of the Windsor & Eton Riverside railway station.
