Demai (Hebrew: דְּמַאי, is the third tractate of Seder Zeraim ("Order of Seeds") of the Mishnah and of the Talmud. It deals with the Jewish legal concept of demai, meaning doubtfully tithed produce, and concerns the laws related to agricultural produce about which it is suspected that certain obligatory tithes have not been separated in accordance with requirements derived from the Torah. The tithes in question are ma'aser rishon (the first tithe, for the Levite), terumath ma'aser (the Levite's tithe to the kohen), and ma'aser sheni (the second tithe, for the owner to consume in Jerusalem) or ma'aser ani (the tithe for the poor), depending on the year of the Sabbatical year cycle.
The tractate consists of seven chapters and has a Gemara only in the Jerusalem Talmud. There is a Tosefta of eight chapters for this tractate.
