Nitzanei Oz (Hebrew: נִצָּנֵי עֹז, ניצני עוז, lit. Buds of Strength) is a moshav in central Israel. Located in the Sharon plain near the Green Line and Tulkarm, it falls under the jurisdiction of Lev HaSharon Regional Council. In 2006 it had a population of 811.
The village was founded in 1951 as a Nahal settlement, before being converted to a civilian moshav in 1958. Due to its proximity to the border with Jordan, it was affected by attacks and infiltrations by Palestinians until the Six-Day War in 1967.
