Eliahu (Eli) ben Shaoul Cohen (Hebrew: אֱלִיָּהוּ בֵּן שָׁאוּל כֹּהֵן, 16 December 1924 – 18 May 1965) was an Israeli spy. He is best known for his work in Syria, where he developed close relationships with the political and military hierarchy and became the Chief Adviser to the Minister of Defense. He was eventually exposed and executed in Syria in 1965. The intelligence he gathered is claimed to have been an important factor in Israel’s success in the Six Day War.
In 2005, he was voted the 26th-greatest Israeli of all time, in a poll by the Israeli news website Ynet to determine whom the general public considered the 200 Greatest Israelis.
