Issam Rajji (Arabic: عصام رجي) (born 1944 in Kfarshima, died 2001 Lebanon) was a Lebanese singer lyricist and composer most prominent during the 1970s and 80s.

[citation needed] Rajji went to Jordan for a while during the Lebanese civil war and married a Jordanian woman Nawal Elias and had three children with her Layal, Rami and Sariya.

He and his family also lived in Oman for a long period of time but then returned permanently to Lebanon in 1993 after the civil war.

[2] When once asked about how he felt about dying, Rajji replied:“I hate death because it would separate me from the people I love.”[3] Best known for his songs "Lagetek" ("When I Met You...") and "Yawmain wa Shahrain" ("Two Days and Two Months"), Raiji also earned roles in Lebanon's top musicals and plays in the 1970s and 1980s with the Rahbani brothers, Sabah, Shoushou and Nabih Aboulhosn.

Rajji was a composer, and beside writing a great deal of his own music, he also wrote for Sabah "Laylitna Saidi" ("Happy is our Night") and "Ya Nas Dinyi Doulab" ("Oh People, Life is like a Wheel").
