Which apostle betrayed Jesus with a kiss?

Judas Iscariot was the apostle who betrayed Jesus with a kiss. According to the canonical Gospels, Judas used the kiss in the Garden of Gethsemane to identify Jesus for the arresting crowd.

Judas was one of the Twelve Apostles and, in the Gospel accounts, agreed to hand Jesus over to the authorities for thirty pieces of silver. The kiss functioned as a prearranged sign because Jesus could otherwise be difficult for the arresting group to identify in the darkness.

The betrayal appears in Matthew, Mark, and Luke, while John describes Judas arriving with an armed group but does not narrate the kiss itself. A common mix-up is confusing Judas Iscariot with the apostle Jude, also called Thaddeus; they are treated as different figures in the New Testament. Later Christian tradition made Judas's name a byword for treachery.
