The Ascension of Jesus (anglicized from the Vulgate Latin Acts 1:9-11 section title: Ascensio Iesu) is the Christian teaching found in the New Testament that the resurrected Jesus was taken up to heaven in his resurrected body,^{[Acts 1:9-11]} in the presence of eleven of his apostles, occurring 40 days after the resurrection. In the biblical narrative, an angel tells the watching disciples that Jesus' second coming will take place in the same manner as his ascension.^[1]

The Ascension of Jesus is professed in the Nicene Creed and in the Apostles' Creed. The Ascension implies Jesus' humanity being taken into Heaven.^[2] The Feast of the Ascension, celebrated on the 40th day of Easter (always a Thursday), is one of the chief feasts of the Christian year.^[2] The feast dates back at least to the later 4th century, as is widely attested.^[2]
