Nizar Zakka (Arabic: نزار زکا) is a Lebanese national who was arrested by Iran in 2015, and was imprisoned until 2019 on charges of espionage for the United States.

Zakka worked as an Internet freedom advocate and served as secretary general of the Arab Information and Communications Technology (ICT) Organization (IJMA3) in Washington, D.C., and is a US permanent resident.

[2] Nizar Zakka was born in Lebanon,[3] and holds permanent-resident status in the U.S.[4] He attended the Riverside Military Academy in Gainesville, Georgia, for high school, graduating in 1985.

[6] As evidence, Iranian state TV displayed a photo of Zikka in army-style fatigues, which Zakka's family identified from a homecoming parade he participated in as an alumnus of his military high school in Georgia.

Lawmakers also stressed the need to "make the release of U.S. citizens and legal permanent resident aliens held hostage by the Iranian government the highest of priorities."
