Sde Ya'akov is a religious moshav in northern Israel. Located near Kiryat Tiv'on, it falls under the jurisdiction of Jezreel Valley Regional Council. Sde Ya'akov was established in 1927, largely from pioneers who had settled in Sheikh Abreik after its purchase by the Jewish Agency. It was the first settlement founded by Hapoel HaMizrachi and was named for Yitzchak Yaacov Reines, founder of the Mizrachi movement.
Sde Ya'aqov has a population of over 1,103 people.
