An antiphon so called from its first line, Ave regina caelorum (Hail, Queen of Heaven). It is one of the four Antiphons of the Blessed Virgin sung in the Divine Office in turn throughout the year, and is assigned thus from Compline of 2 February (even when the Feast of the Purification is transferred) to Holy Thursday exclusively.
