Avihayil (Hebrew: אֲבִיחַיִל, lit. Father of strength) is a moshav in central Israel. Located to the north-east of Netanya, it falls under the jurisdiction of Hefer Valley Regional Council. In 2012 it had a population of 1,394.
In 1921 veterans of the Jewish Legion of World War I settled on desert land allocated to it by the British Mandate government in the northeastern Negev, near Tel Arad. However, the settlement was abandoned after no water was found.
In 1946 Avihayil merged with the neighboring moshav, Ein HaOved. The founders were immigrants from Canada, Russia and the United States, as well as several native Israelis. In 1967 there were 605 inhabitants, and its economy was based on intensive mixed farming including citrus. It established "Beit HaGedudim", a museum of the Jewish Legion and clubhouse for veterans.
In 1947, it had a population of 600.
