The Liturgy of the Presanctified Gifts also referred to as The Divine Liturgy of Saint Gregory the Dialogist is a Byzantine Rite liturgical service which is conventionally performed on the Wednesdays and Fridays of Great Lent and the first three days of holy week. Communion is received from Gifts (the Body and Blood of Christ) that are sanctified (consecrated) in advance, hence its name; this Divine Liturgy has no anaphora (Eucharistic Prayer).

Distinctive Lenten music is only sung in these services. Also unique to the Presanctified service is the chanting of the Songs of Ascents (Psalms 120-134).
