Bensayah Belkacem (born September 10, 1962) is a citizen of Bosnia, previously held in the United States Guantanamo Bay detainment camps, in Cuba.

Belkacem and five other men, native-born Algerians who were charity workers and colleagues of his, were arrested on suspicion of plotting to bomb the American embassy in Bosnia.

After reviewing their cases, US District Court Judge Richard J. Leon ruled each of the five was being held illegally, but he ordered the continued detention of Belkacem.

[12] On October 12, 2004, the Department of Defense released 40 pages of unclassified documents related to Belkacem's Combatant Status Review Tribunal.

[16] According to The Blog of Legal Times, a partially declassified brief to the appeal court by one of Belkacem's lawyers, of Wilmer Cutler Pickering Hale and Dorr, had challenged Leon's reasoning because he had relied on "unfinished, conclusory intelligence reports and uncorroborated assertions from anonymous sources.

Judge Douglas H. Ginsburg, writing for the panel, said that the U.S. Government had presented "no direct evidence of actual communication between Bensayah and any al-Qaeda member".

[10] According to The New York Times, "Still, Judge Ginsburg's opinion suggested that the appeals court ruling turned less on the recategorization of Mr. Bensayah's alleged ties to al-Qaeda than on skepticism about the basic credibility of the evidence the government presented against him."
