Sergey Vladilenovich Kiriyenko (born 26 July 1962) is a Russian public official and administrator. He is best known for a brief term as head of government in 1998 and for later managing key state sectors. The Russian spelling of his name appears in official records; he is widely described in sources as a politician and technocratic manager.

Career

Kiriyenko rose from technical and managerial posts to national office in the 1990s. He was appointed Prime Minister of the Russian Federation on 23 March 1998 and served until 23 August 1998 under President Boris Yeltsin. His appointment, at an unusually young age for the office, attracted attention and debate. During his premiership he confronted acute fiscal and banking stresses that culminated in the financial crisis of 1998; the crisis and the resulting political fallout led to his resignation from the post.

After leaving the premiership, Kiriyenko continued to occupy senior roles in government and state sector enterprises. From 2005 until 2016 he was head of the Russian state nuclear corporation Rosatom, where he oversaw organizational consolidation and international contracts that expanded the corporation's global presence. On 5 October 2016 he returned to the Kremlin administration when he was appointed First Deputy Chief of Staff of the Presidential Administration of Russia.

Responsibilities and areas of focus

Across different posts Kiriyenko has been associated with economic policy, industrial management and state project delivery. His work at Rosatom involved coordination of complex technology projects, export negotiations and oversight of a major state enterprise. In the Presidential Administration he has been involved in coordinating domestic policy priorities and managing relations among ministries and state bodies.

Significance and public perception

Kiriyenko is often characterized as a technocrat: a manager who combines administrative experience with expertise in large-scale state enterprises. His brief premiership is remembered mainly for its timing amid the 1998 financial collapse, while his longer tenure at Rosatom is cited for strengthening a strategic sector. Public and expert assessments vary; some praise his organizational skills and continuity of management, while others critique policy outcomes during periods of economic stress.
