Omar al-Bayoumi (; born ) is a Saudi national linked to two of the 9/11 hijackers in the United States, though he says he simply befriended the pair rather than ran them as agents. Files of the US FBI dating to before the attacks demonstrate that he was a Saudi Arabian intelligence agent. An FBI report declassified in September 2021 lays out evidence that al-Bayoumi had links to known terrorists, provided significant support to 9/11 hijackers Nawaf al-Hazmi and Khalid al-Mihdhar upon their arrival in the US, and communicated with a key logistics facilitator for Osama bin Laden, each time immediately following significant logistics support to Hazmi and Mihdhar. An FBI report declassified in March 2022 lays out evidence that "there is a 50/50 chance [al-Bayoumi] had advanced knowledge the 9/11 attacks were to occur." from the two Islamists he befriended that were involved in plotting 9/11. al-Bayoumi also helped the Islamists find housing in San Diego. Saudi Arabia claims that al-Bayoumi is not an agent of theirs.

Income Al-Bayoumi was probably born around 1958, but virtually nothing is known of al-Bayoumi's early life.

Until 1994, he lived in Saudi Arabia, working for the Saudi Ministry of Defense and Aviation, a department headed by Prince Sultan bin Abdul Aziz. In August 1994, al-Bayoumi moved to the United States and settled in San Diego, California, where he became involved in the local Muslim community. He was perceived as being very inquisitive, and was known to always carry around a video camera. According to several sources, al-Bayoumi was strongly suspected by many residents to be a Saudi government spy. The man the FBI considered their "best source" in San Diego said that al-Bayoumi "must be an intelligence officer for Saudi Arabia or another foreign power," according to Newsweek magazine. During this time, al-Bayoumi was purportedly a San Diego State University student learning remedial English in the United States as part
