Ryspek Akmatbayev (1960–2006) (Russian: Рысбек Акматбаев) was a Kyrgyz businessman, politician and alleged criminal leader. Under President Askar Akayev, Akmatbayev and a number of other alleged criminal figures including Bayaman Erkinbayev were facing a variety of criminal charges including murder. Seeing an opportunity during the 2005 Tulip Revolution, the mafia participated heavily in the coup and subsequently won positions in the post-revolutionary government. Ryspek was elected to parliament in April 2006. However, a power struggle emerged, and several politicians including Erkinbayev, Raatbek Sanatbayev and Ryspek's own brother Tynychbek were assassinated, the latter having died during a prison riot orchestrated by another Kyrgyz criminal, thief in law Aziz Batukayev.
