The Burning of Judas is an Easter-time ritual in many Orthodox and Catholic Christian communities, where an effigy of Judas Iscariot is burned. Other related mistreatments of Judas effigies include hanging, flogging, and exploding with fireworks.
Though not an official part of the Easter liturgical cycle, the custom is typically a part of the reenactment of the story of the Passion that is practiced by the faithful during Easter. Customs vary, but the effigy of Judas is typically hanged (reenacting Matthew 27:5) on Good Friday, then burned on the night of Easter Sunday.
The burning of Judas was once widely practiced across Europe, and is still practiced in parts of Mexico and other Orthodox or Catholic Christian countries.
