Nahum Admoni (Hebrew: נחום אדמוני; born November 21, 1929) is an Israeli former intelligence officer who served as the Director-General of the Mossad from 1982 to 1989.

There he rejoined the Israeli intelligence community, working his way up the chain of command to be Mossad Director Yitzhak Hofi's deputy.

In 1982 the designated director of the Mossad Yekutiel Adam was killed in 1982 Lebanon War and Admoni was chosen to replace him.

Admoni was criticized by the Kahan Commission for not warning the cabinet before allowing the Gemayel Phalangists into the camps, though no action against him was recommended.
