United Nations Security Council resolution 517, adopted on 4 August 1982, after recalling resolutions 508 (1982), 509 (1982), 512 (1982), 513 (1982), 515 (1982) and 516 (1982), the council again demanded an immediate cessation of military activities between Israel and Lebanon, and the withdrawal of Israeli forces from Lebanese territory.

The resolution then took note of the Palestine Liberation Organization's (PLO) decision to move its forces from Beirut, and requested the secretary-general to report back on the situation no later than 1000 hours (ET).

The resolution was adopted by 14 votes to none, with one abstention from the United States.
