Filipp Filippovich Sidorsky (; 21 August 1937 – 27 February 2023) was a Soviet and Russian diplomat. He served in various diplomatic roles from 1966 onwards, and was Ambassador of Russia to Uzbekistan between 1992 and 1997, and to Bosnia and Herzegovina from 1998 to 2000. Career Sidorsky was born on 21 August 1937, in Moscow, then part of the Russian Soviet Federative Socialist Republic, in the Soviet Union. He initially began working as a projectionist in 1954, and later as an electrician, and a tunneller at Metrostroy. He began his career in the Soviet Foreign Ministry in 1966, graduating from Moscow State Institute of International Relations that year, and entering the diplomatic service. Sidorsky worked in various diplomatic positions in the Soviet, and later Russian, foreign ministry, and its diplomatic missions abroad. He graduated from the Diplomatic Academy of the Ministry of Foreign Affairs in 1978, and worked in the Soviet embassy in Iran, and from 1988 to 1992, was Minister-Counselor of the embassy in Afghanistan.

Diplomatic relations between the Russian Federation and the Republic of Uzbekistan were officially established on 20 March 1992. The Treaty on the Fundamentals of Interstate Relations, Friendship and Cooperation was signed several months later, on 30 May 1992. The Tajikistani Civil War began shortly after Sidorsky's arrival in post, with the suggestion that Russian military forces were taking sides within the country.
