The Solemnity of the Most Holy Trinity, commonly known as Trinity Sunday, is a liturgical celebration in the Catholic Church that honors the Christian doctrine of the Trinity: one God in three persons – the Father, the Son (Jesus Christ), and the Holy Spirit.

This feast is celebrated on the Sunday following Pentecost, marking the conclusion of the Easter season. The liturgical color associated with this celebration is white.
