Proverbs 12 is the twelfth chapter of the Book of Proverbs in the Hebrew Bible or the Old Testament of the Christian Bible. The book is a compilation of several wisdom literature collections, with the heading in 1:1 may be intended to regard Solomon as the traditional author of the whole book, but the dates of the individual collections are difficult to determine, and the book probably obtained its final shape in the post-exilic period. This chapter is a part of the second collection of the book.

Some early manuscripts containing the text of this chapter in Hebrew are of the Masoretic Text, which includes the Aleppo Codex (10th century), and Codex Leningradensis (1008).

There is also a translation into Koine Greek known as the Septuagint, made in the last few centuries BC.
