The military secretary to the Prime Minister (Hebrew: המזכיר הצבאי של ראש הממשלה, HaMazkir HaTzva'i Shel Rosh HaMemshala), is the senior military adviser to the Prime Minister of Israel on military and national security issues.

As a member of the Military Staff, the position is privy to most products of the Israeli Intelligence Community.

Earlier military secretaries held the rank of Lieutenant Colonel (Hebrew: סגן אלוף).

It has been suggested that the raising of status of the military secretary has resulted in military considerations unduly weighing upon Israel's national security policy at the expense of other considerations.

that to remedy this, the position of military secretary ought to be held by a lower rank.
