What was the name of the disciple who betrayed Jesus according to the Gospels?

The Gospels identify Judas Iscariot as the disciple who betrayed Jesus. He is portrayed as one of the Twelve and as the person who led the arresting group to Jesus in the Garden of Gethsemane.

Matthew, Mark, and Luke describe Judas agreeing to hand Jesus over, while John also presents him as a member of the Twelve who later betrays Jesus. The Gospel accounts connect the betrayal with a kiss or greeting that identifies Jesus to those who came to arrest him.

Judas Iscariot is different from Judas son of James, another figure in apostolic lists. After Jesus’ death, Matthew describes Judas dying by suicide, while Acts gives a different account of his death. These differences are among the details scholars compare when studying the New Testament narratives.
