Katzir (Hebrew: קציר) is a Jewish locality in northern Israel. Located south-west of Umm al-Fahm and close to the Green Line, it falls under the jurisdiction of Menashe Regional Council. In 2011 it had a population of 2,484.
The village was established in 1982 by Hitahdut HaIkarim on land owned by the Jewish Agency, and was initially a Community settlement. In 1993 it was merged with neighbouring Harish to form Katzir-Harish local council. However, in 2012 the two were separated, with Harish remaining a local council and Katzir reverting to the jurisdiction of Menashe Regional Council.
