A '''prokeimenon''' (or prokimen; plural: prokeimena) is a liturgical verse or scriptural passage sung or read before the apostolic reading. It can serve as an introduction to the theme of the particular reading on feast days. On most Sundays, the prokeimenon of the resurrection, for the tone of the week (from the [[Octoechos]]), is chanted.

At the [[Divine Liturgy]], the prokeimenon is proclaimed after the singing of the [[Trisagion]] [[hymn ]] to introduce the [[apostolos]] reading. The deacon says, "Let us attend." At this point the Greek and Slavic practices diverge.
