The Jamaat al Muslimeen coup attempt was an attempt to overthrow the government of Trinidad and Tobago, instigated on Friday, 27 July 1990. Over the course of six days, Jamaat al Muslimeen, a radical extremist Islamist group, held hostages (including Prime Minister A. N. R. Robinson and other government officials) at the Red House and at the headquarters of the state-owned national television broadcaster, Trinidad and Tobago Television (TTT). On 1 August, the insurgents surrendered. They were charged with treason, but were ordered released by the Court of Appeal. Twenty four people were killed and many more were injured in the coup.

The Jamaat al Muslimeen (Arabic: جماعة المسلمين, romanized: al-Jamā‘at al-Muslimīn, also transliterated as Jamaat-ul Muslimeen or Jama'at al-Muslimeen, "School of Muslims", "Group of Muslims", "The Muslim Group", "The Muslim Assembly", "The Muslim Society", "The Muslim Community") is an Islamic group in Trinidad and Tobago.

The organisation is responsible for the Jamaat al Muslimeen coup attempt of July 1990, in which its leader, Imam Yasin Abu Bakr, led members of the Jamaat in an attempted coup d'état against the unpopular Government of Trinidad and Tobago. Over a six-day period members of the government, including then-Prime Minister A.N.R. Robinson, were held hostage at gunpoint, while the group occupied a television station and parliament, and chaos and looting broke out in the streets of the capital, Port of Spain.
