Mishmar HaEmek (Hebrew: מִשְׁמַר הָעֵמֶק, lit. Guardian of the Valley)  is a kibbutz in northern Israel. Located in the western Jezreel Valley, it falls under the jurisdiction of Megiddo Regional Council. In 2006, it had a population of 964.
During the autumn of 1942, when there were fears of a German victory in the Middle East, Mishmar HaEmek was used as a training camp by the British army. 160 Jewish volunteers, who later were to become members of the Palmach branch of the Haganah, were trained by Royal Engineers in sabotage and wireless operation. Several tons of explosives were hidden in caches in case the area came under German occupation. This program was terminated immediately upon the training of the volunteers, and orders issued for the collection of all equipment and explosives to be returned to the British. 
In 1947, Mishmar HaEmek had a population of 550. The Jewish National Fund and Worton Hall Studios made a 1947 movie called The Great Promise (Dim'at Ha'Nehamah Ha'Gedolah), and a number of the scenes were filmed here.  
On 4 April 1948, the kibbutz came under full scale attack by the Arab Liberation Army. The attack began with an artillery barrage from seven artillery pieces supplied by the Syrian Army. In the following counter-attack the Haganah destroyed eight neighbouring Arab villages.
The main source of income is Tama, a plastic factory based on the kibbutz with additional plants around the country and the world. The kibbutz also raises chickens and farms about 7,000 dunams. Idea, a high-tech company based in Mishmar HaEmek, is responsible for the database system of the Holocaust museum Yad Vashem.
