Uncial 0171 (in the Gregory-Aland numbering), ε 07 (Soden) are two vellum leaves of a late third century (or beginning of the fourth) Greek uncial Bible codex containing fragments of the Gospel of Matthew and the Gospel of Luke.

It is classed as a "consistently cited witness of the first order" in Nestle-Aland's Novum Testamentum Graece.

Hermann von Soden knew the first fragment only in time to include it in the list of addenda in 1913.

[10] Kurt Treu identified the Matthew and Luke portions as the work of the same scribe on the same codex.

[11] Later again, Neville Birdsall observed that a lower portion of the manuscript had been overlooked in the editio princeps.
