The second tithe (Hebrew: ma'aser sheni מעשר שני) is a tithe mentioned in the Hebrew Bible and practised within Orthodox Judaism. It is distinguished from the first tithe (Hebrew: ma'aser rishon מעשר ראשון), the third or poor tithe, and the terumat hamaaser.
In the days of the Temple in Jerusalem, the second tithe involved the setting aside of one tenth of specific agricultural produce during the first, second, fourth and fifth years of each seven-year cycle, for the purpose of taking it to the holy city of Jerusalem, and consuming it there.
