Lectionary 183, designated by siglum ℓ 183 (in the Gregory-Aland numbering) is a Greek manuscript of the New Testament, on parchment, written in uncial letters. Westcott and Hort labelled it by 38e, Scrivener by 257e. Paleographically usually it has been assigned to the 10th century. The manuscript has some lacunae at the end and inside, but they were supplied by a later hand. It is faded in parts. It forms part of the British Library Arundel Manuscripts.
