|Founded by||Romanian immigrants|
Olesh (Hebrew: עֹלֶשׁ, עולש, lit. Chicory) is a moshav in central Israel. Located in the Sharon plain, it falls under the jurisdiction of Hefer Valley Regional Council. In 2015 it had a population of 1,067.
The moshav was founded in 1951 by immigrants from Romania on land south of the Arab village of Qaqun, which had been depopulated as a result of the 1948 Arab–Israeli War. It was initially named Be'erotayim Bet, but was later renamed Olesh due to the large chicory plants in the area.
