Zeno of Tarsus was a Stoic philosopher active in the late 3rd and early 2nd centuries BCE. He was from the city of Tarsus in Cilicia and studied under the influential Stoic thinker Chrysippus in Athens. Upon Chrysippus's death around 206 BCE, Zeno succeeded him as the third head, or scholarch, of the Stoic school.

Ancient sources report that Zeno of Tarsus wrote very little, and no works by him survive today. He is not credited with any specific book titles. According to the ancient biographer Diogenes Laertius, he left behind few writings but had many students.

His main historical importance comes from his role as a successor who maintained the institutional continuity of the Stoic school after Chrysippus. However, scholars note that he is not remembered for developing new philosophical ideas. Ancient accounts characterize him as an unoriginal figure who did not innovate upon established Stoic doctrine. He was succeeded as head of the school by Diogenes of Babylon. For these reasons, Zeno of Tarsus is primarily seen as a transitional figure who helped preserve the school's leadership during his tenure.
