Tractate Temurah (Hebrew: תמורה, literally: "exchange") is a tractate of the Mishnah, Tosefta, and Babylonian Talmud, which is part of the Order of Kodashim.

Its main subject is the Biblical prohibition (Leviticus 27:10) against attempting to switch the sanctity of an animal that has been sanctified for the Temple in Jerusalem with another non-sanctified animal.

[citation needed] The Mishnah's seven chapters cover the following topics: This prohibition of exchange was counted by Maimonides as comprising 3 of the 613 commandments.
