Sde Yitzhak (Hebrew: שְׂדֵה יִצְחָק, lit. Field of Yitzhak) is a moshav in northern Israel. Located in the eastern Sharon plain to the south-east of Hadera, it falls under the jurisdiction of Menashe Regional Council. In 2006 it had a population of 264.
The village was established in 1951 on the former site of Lahavot Haviva, which had moved to its present location three kilometres east the previous year. The founders were immigrants from Poland. The moshav was named after Yitzhak Sadeh, a founder of the Palmach.
