Mukhtar Kabyluly Ablyazov (alternatively, Muhtar Qabyluly Abilyazov, born 16 May 1963) is a Kazakh dissident, politician, economist, businessman, and banker.

He was the founder of Democratic Choice of Kazakhstan (DCK), a political party that disbanded in 2005. He is also the author of Ablyazov against Nazarbayev.

Ablyazov served as the Chairman of the Board of Directors of BTA Bank from 2005 to 2009. During Ablyazov's leadership, BTA Bank reported dynamic growth, and became one of the most promising banks in the CIS.

While Chairman of BTA Bank, Ablyazov is alleged to have embezzled or misappropriated up to $6 billion into shell companies and offshore bank accounts. Ablyazov's case is one of the largest financial fraud cases in history. Ablyazov stated that BTA Bank assets were concealed to guard against forced nationalization. Judge Sir Nigel John Martin Teare said that Ablyazov had committed a “fraud on an epic scale” through use of offshore holding companies.
