In the Eastern Orthodox Church, Orthros (Greek (ὄρθρος, meaning "early dawn" or "daybreak") or Oútrenya (Slavonic Оўтреня) is the last of the four night offices, which also include vespers, compline, and midnight office. In traditional monasteries it is held daily so as to end at sunrise. In many parishes it is held only on Sundays and feast days. It is often called matins after the office it most nearly corresponds to in Western Christian churches.
Orthros is the longest and most complex of the daily cycle of services. It is normally held in the early morning, often — always in monasteries — preceded by the midnight office, and usually followed by the First Hour. On great feasts it is held as part of an all-night vigil commencing the evening before, combined with an augmented great vespers and the first hour. In the Russian tradition, an all-night vigil is celebrated every Saturday evening, typically abridged, however, in spite of its name, to as short as two hours. In the Greek parish tradition, orthros is normally held just before the beginning of the divine liturgy on Sunday and feast day mornings.
The akolouth (fixed portion of the service) is composed primarily of psalms and litanies. The sequences (variable parts) of matins are composed primarily of hymns and canons from the octoechos (an eight-tone cycle of hymns for each day of the week, covering eight weeks), and from the menaion (hymns for each calendar day of the year). During great lent and some of the period preceding it, some of the portions from the octoechos and menaion are replaced by hymns from the triodion and during the paschal season with material from the pentecostarion. On Sundays there is also a gospel reading and corresponding hymns from the eleven-part cycle of resurrectional gospels.
- All of the psalms used herein are numbered according to the Septuagint, which is the official version of the Old Testament used by the Orthodox Church. To find the corresponding KJV numbering, see the article Kathisma.
- Matins usually opens with what is called the "Royal Beginning", so called because the psalms (19 and 20) speak of a king. The royal beginning is not used in Greek parish practice; also, it is omitted at all-night vigil. During Paschal season it is replaced by the paschal troparion sung thrice):
- The priest's opening blessing: Blessed is our God ..., reader: Amen. and the usual beginning.
- Psalms 19 and 20, during which the priest performs a full censing of the temple (church building and worshippers).
- Glory... Both now... and the trisagion prayers.
- The Royal troparia:
- A brief litany by the priest (not the deacon as is usual for litanies)
- Ekphonesis by the priest: Glory to the holy, consubstantial, life-giving and undivided trinity, always, now and ever, and unto the ages of ages
- The Six Psalms (3, 37, 62, 87, 102, and 142),[note 1] during which the priest says twelve silent prayers: six in front of the Holy Table (altar), and six in front of the Holy Doors
- The Litany of Peace (also known as the Great Litany)
- God is the Lord ... and the apolytikion (troparion of the day)
- The Psalter (either two or three sections, depending upon the liturgical season). For each section the following order is followed:
- On Sundays: Evlogetaria (Blessed are you, O Lord, teach me your statutes)
- The Little Litany
- On Sundays and Feast Days:
- The Hypakoë is chanted to prepare for the message of the Gospel reading
- The Anavathmoi ("hymns of ascent") based on Psalms 119-133, called the Song of Degrees)

- The order of the Matins Gospel

- The exapostilaria (hymns related to the day's gospel, or the day's feast)
- The lauds (Greek: Ainoi, praises): Psalms 148, 149, 150; stichera are interspersed between the final verses on days the great doxology is sung,
- The ending:
- The doxastikon (the glory hymn), when chanted properly in Byzantine music is the longest, and usually the richest, hymn of the service.
- Sundays and feast days: the Great Doxology is chanted, followed by the apolytikion, the two litanies and the dismissal
- Weekdays: the Small Doxology is read, followed by the first litany, the aposticha, It is good to give praise unto the Lord..., the trisagion sequence followed by the apolytikion, and the second litany (there is no dismissal)
- The First Hour
In very traditional monasteries, readings from the Church Fathers are read after each of the sessional hymns.
Types of orthros
There are seven types of Matins:
- Sunday orthros—The longest of the regular orthros services - Gospel Reading and Great Doxology. If this service is celebrated in its entirety it can last up to six hours but is typically abridged.
- Daily orthros—Celebrated on most weekdays - No gospel reading, Small Doxology.
- Feast-day orthros—Very similar to Sunday orthros, excluding those parts which are strictly resurrectional in nature - gospel reading and Great Doxology.
- Lenten orthros—Weekdays during great lent, the Wednesday and Friday of Cheesefare Week, and, optionally when there is no divine liturgy, on the weekdays of the lesser fasting seasons (Nativity Fast, Apostles' Fast and Dormition Fast). The service follows the order of daily orthros but with penitential material added (hymns and prayers), most days have three kathismata from the Psalter, "God is the Lord" is replaced by "Lenten Alleluia" (from which fact these days are identified as "days with Alleluia"). The petition: "O God, save your people and bless your inheritance ..." is read by the priest. There is no gospel reading. The Small Doxology is read and there is special lenten ending of the service, including the Prayer of St. Ephraim.
- Great and Holy Friday Orthros — Twelve Passion Gospels are interspersed throughout the service; Antiphons are used between the Gospels (these originated in a different office).
- Great and Holy Saturday Orthros—Lamentations are chanted around the epitaphios, interspersed between the verses of Psalm 118. Contains some elements of the old cathedral office: reading of three pericopes (lessons from the Old Testament, epistle and Gospel) at the end - Great Doxology followed by the procession with epitaphios.
- Paschal orthros—Celebrated during Bright Week, from the Sunday of Pascha (Easter) through Bright Saturday. The service is vastly different from the rest of the year; only the ektenias, canon (the canticles of which are omitted) and lauds are the same; everything else, including the psalms, are replaced by special paschal hymns. The priest vests fully in his eucharistic vestments on the Sunday of Pascha and wears a phelonion throughout the week. There is no doxology at all.

- Canonical hours
- Anglican Morning Prayers
- Night Hours
- Book of Hours
- Matins in Lutheranism
- One of the oldest elements in the orthos service and according to a pious tradition said to recall the Last Judgement, as Psalm 103 at vespers recalls the creation.
