O salutaris Hostia (Latin, "O Saving Victim" or "O Saving Sacrifice"), is a section of one of the Eucharistic hymns written by St Thomas Aquinas for the Feast of Corpus Christi. He wrote it for the Hour of Lauds in the Divine Office. It is actually the last two stanzas of the hymn Verbum supernum prodiens, and is used for the Adoration of the Blessed Sacrament. The other two hymns written by Aquinas for the Feast contain the famous sections Panis angelicus and Tantum ergo.
