Degania Alef (Hebrew: דְּגַנְיָה א', IPA: ['dɡanja 'alef]) is a kibbutz in northern Israel. The Jewish communal settlement (kvutza) started off in 1910, making it the earliest socialist Zionist farming commune in the Land of Israel. Its status as "the mother of all kibbutzim" is sometimes contested based on a later distinction made between the smaller kvutza, applying to Degania in its beginnings, and the larger kibbutz.

It falls under the jurisdiction of the Emek HaYarden Regional Council. Degania Alef and its neighbor Degania Bet both lie between the southern shore of the Sea of Galilee and the Jordan River. As of 2021 it had a population of 524.
