A New Testament Lectionary is a handwritten copy of a lectionary, or book of New Testament Bible readings. Lectionaries may be written in majuscule or minuscule Greek letters,^[1] on parchment, papyrus, vellum, or paper.^[2]

New Testament lectionaries are distinct from:

• New Testament papyri
• New Testament majuscules
• New Testament minuscules

Lectionaries which have the Gospels readings are called Evangeliaria or Evangelistaria, those which have the Acts or Epistles, Apostoli or Praxapostoli. They appear from the 6th century.

Before Scholz only 57 Gospel lectionaries and 20 Apostoloi were known. Scholz added to the list 58-181 Evangelistarioi and 21-58 Apostoloi.^[3] Gregory in 1909 enumerated 2234 lectionaries. To the present day 2484 lectionary manuscripts have been catalogued by the (INTF) in Münster.

• The numbers (#) are the now standard system of Caspar René Gregory (Gregory–Aland).
• Dates are estimated to the nearest century (except lectionaries dated by scribes which are shown in the Date column).
• Content only the Gospel lessons (Evangelistarion), and other lessons from the rest of the NT apart from Revelation (Apostolos). Sometimes the surviving portion of a codex is so limited that specific books, chapters or even verses can be indicated. Linked articles, where they exist, generally specify content in detail, by verse.
