In 1895 the founders of the town of Hadera planted Gan Shmuel, a grove of etrogs. The lands of Gan Shmuel were transferred to the Jewish National Fund and a small group of pioneers took upon itself to tend to the orchards live in a multi-story house in 1913. The group was recognized as a kibbutz in 1921. The first stable group formed in 1923 and its members were considered the founders of Gan Shmuel. The kibbutz buildings were designed by Arieh Sharon in keeping with the principles of Bauhaus architecture. 
The kibbutz is the owner (43%) of the publicly traded beverage company Gan Shmuel Foods Ltd. Established in 1941, the company exports products to 35 countries throughout Europe and the Far East and is the largest exporter of processed foods in Israel. Since Gan Shmuel Foods' merger with Ganir Ltd. in 2007, Gan Shmuel Group owns the Primor juice brand.
The kibbutz is host to the Hapoel Gan Shmuel Menashe basketball team, which previously played in the top division of Israeli basketball.
