O Salutaris Hostia (sălˌyōtârˈĭs, säˌlōtäˈrĭs) [key] [Lat., = O saving victim], hymn to the Host, one of the two hymns regularly sung at the Benediction of the Blessed Sacrament in the Roman Catholic Church. The other hymn is Tantum ergo. O Salutaris is really the last two stanzas of a Corpus Christi hymn, Verbum supernum prodiens, probably written by St. Thomas Aquinas.
