Ra'anana (Hebrew: רַעֲנָנָּה, lit. "Fresh") is a city in the southern Sharon Plain of the Central District of Israel. It was founded in 1922 as an American-Jewish settlement, c.1 km south of the Palestinian village of Tabsur, where an important World War I battle had taken place four years previously.Bordered by Kfar Saba and Hod HaSharon on the east and Herzliya on the southwest, it had a population of 75,421 in 2019. While the majority of its residents are native-born Israeli Jews, a large part of the population consists of Jewish immigrants from the Americas and Europe.
Ra'anana's industrial park, built over the depopulated village of Tabsur, is home to global and local start-up companies. It was designated a "Green City" by the World Health Organization in 2005.
