Kfar Sirkin was founded in 1933 and was named for the Zionist leader Nachman Syrkin. It served as a Jewish stronghold during the 1936–1939 Arab revolt in Palestine, with the Haganah using the village to fight off attacking Arab forces and to store weapons which were illegal under the British Mandate rule of the time.
Today, the village is agricultural. An Israel Defense Forces military base, and former RAF airfield, is located to the north-west of the village.
