The ministry of Jesus, in the canonical gospels, begins with his baptism near the River Jordan by John the Baptist, and ends in Jerusalem in Judea, following the Last Supper with his disciples. The Gospel of Luke states that Jesus was "about 30 years of age" at the start of his ministry. A chronology of Jesus typically sets the date of the start of his ministry at around AD 27–29 and the end in the range AD 30–36.

The baptism of Jesus, the ritual purification of Jesus with water by John the Baptist, was a major event described in the three synoptic Gospels of the New Testament. It is considered to have taken place at Al-Maghtas, today located in Jordan.
