Trinity Sunday is the first Sunday after Pentecost in the Western Christian liturgical calendar, and the Sunday of Pentecost in Eastern Christianity. Trinity Sunday celebrates the Christian doctrine of the Trinity, the three Persons of God: the Father, the Son, and the Holy Spirit.

Trinity Sunday is celebrated in all the Western liturgical churches: Roman Catholic, Anglican,Lutheran,Presbyterian,United Church of Christ, and Methodist.

The Sundays following Pentecost, until Advent, are numbered from this day. In traditional Catholic usage, the First Sunday After Pentecost is on the same day as Trinity Sunday. In the revised Roman rite, Ordinary Time resumes one week earlier, on the Monday after Pentecost, with the Sundays that would otherwise fall on Pentecost and Trinity Sunday omitted that year. In the Church of England, following the pre-Reformation Sarum use, the following Sunday is the "First Sunday after Trinity", while the Episcopal Church in the United States of America (ECUSA) now follows the Catholic usage, calling it the Second Sunday after Pentecost. The liturgical colour used on Trinity Sunday is white.
