Mark 15 is the fifteenth chapter of the Gospel of Mark in the New Testament of the Christian Bible. This chapter records the narrative of Jesus' passion, including his trial before Pontius Pilate and then his crucifixion, death and entombment. Jesus' trial before Pilate and his crucifixion, death, and burial are also recorded in Matthew 27, Luke 23, and John 18:28–19:42.

The Gospel of Mark is the second of the four canonical gospels and one of the three synoptic Gospels. It tells of the ministry of Jesus from his baptism by John the Baptist to his death, the burial of his body, and the discovery of his empty tomb. It portrays Jesus as a teacher, an exorcist, a healer, and a miracle worker, though it does not mention a miraculous birth or divine pre-existence. He refers to himself as the Son of Man. He is called the Son of God but keeps his messianic nature secret; even his disciples fail to understand him. All this is in keeping with the Christian interpretation of prophecy, which is believed to foretell the fate of the messiah as suffering servant.
