Rosh HaAyin (Hebrew: רֹאשׁ הָעָיִן Hebrew pronunciation: [ˌroʃ häˈʔä.in], lit. Fountainhead) is a city in the Center District of Israel.

Rosh HaAyin was founded in the 1950s near the site of ancient Antipatris and the Arab village of Majdal Sadek (also known as Majdal Yaba). Many of the early residents were Yemenite Jews airlifted to Israel in 1949 and 1950 in Operation Magic Carpet. In the 1990s new neighborhoods were built although the town still has a large Yemenite population.
Rosh HaAyin is named after its location at the mouth of the Yarkon Spring (rosh = head, ayin = spring).
