The angel's name that told the Virgin Mary she would have a child is Gabriel. In the Gospel of Luke, it is stated that the angel Gabriel visited Mary in Nazareth to announce that she would conceive and bear a son whom she would name Jesus. This event is known as the Annunciation and is celebrated by Christians around the world on March 25th as the Feast of the Annunciation. Gabriel is also mentioned in the Old Testament as one of the primary messengers of God and is described as having great power and authority.
