Khalil Izz el-Deen al-Jamal (Arabic: ) (January 21, 1951 – 15 April 1968) was the first Lebanese commando to be killed in action in the Israeli–Palestinian conflict. His death in April 1968 in Jordan, during a skirmish with Israeli forces known as the Battle of Tel Arbaein ("Hill Forty", ()), resulted in hundreds of Lebanese youth joining the Palestinian fedayeen. His funeral, attended by between 150,000 to 250,000 people, was widely seen as an expression of Lebanese solidarity with the Palestinian cause.

Additionally, a helicopter dropped more than 30 paratroopers in the region. They were under the observation of the Palestinian Al Asefa forces which signaled to their comrades to ambush them at Tell Arbaein (تل الأربعين; Hill 40). Khalil was part of the ambushing unit. The guerrilla group divided themselves into three units then clashed with the Israeli troops from three different sides and caused them 10 casualties. The Israeli forces began to regress, carrying their wounded and dead from the area of engagement.
