Codex Seidelianus II designated by He or 013 (in the Gregory-Aland numbering), ε 88 (von Soden), is a Greek uncial manuscript of the four Gospels, dated palaeographically to the 9th century.

The codex contains lists of the κεφαλαια (lists of contents), numbers of the κεφαλαια (chapters) at the margin, the τιτλοι (titles) at the top, the Ammonian Sections but not the Eusebian Canons.

[2] The Greek text of this codex is a representative of the Byzantine text-type.

[3] The codex was brought from the East by Erasmus Seidel at the beginning of the 17th century, together with Codex Seidelianus I. Maturin Veyssière de La Croze bought it 1718, in the same time as Seidelianus I.

One leaf of the codex is housed at Trinity College, Cambridge (B XVII 20.21).
