Lectionary 170, designated by siglum ℓ 170 (in the Gregory-Aland numbering) is a Greek manuscript of the New Testament, on parchment leaves.

[2] The codex contains lessons from the Acts and Epistles lectionary (Apostolarion), on 160 parchment leaves (26.4 cm by 19.7 cm), with lacunae at the beginning and end.

The Menology (folios 114 v – 160) has almost no lessons given at length, but overflows with rubrical directions.

[4] The manuscript was purchased in 1870 by Angela Burdett-Coutts.

[6] Since 1922 the codex is located in the University of Michigan (Ms. 35) at Ann Arbor.
