Barzan Ibrahim al-Hasan al-Tikriti (February 17, 1951 – January 15, 2007) (also known as Barazan Ibrahim al-Tikriti, Barasan Ibrahem Alhassen, and Barzan Hassan) (; Barzān Ibrāhīm al-Ḥasan at-Tikrītī) was one of three half-brothers of Saddam Hussein, and a leader of the Mukhabarat, the Iraqi intelligence service. Despite falling out of favour with Saddam at one time, he was believed to have been a close presidential adviser at the time of his capture. On January 15, 2007, he was hanged for crimes against humanity. The rope decapitated him because wrong measurements were used in conjunction with how far he was dropped from the platform.

Lavorò presso la polizia segreta irachena fin dagli anni settanta ma è a partire dal 1995 che cominciò la sua scalata al potere: divenuto intimo amico e collaboratore di Saddam, il dittatore iracheno lo pose in quell'anno a capo del Mukhabarat ed in questa veste Barzan divenne uno degli esponenti del regime più spietati nel reprimere le opposizioni interne.
