Yuri Petrovich Shchekochikhin (Russian: Ю́рий Петро́вич Щекочи́хин, IPA: [ˈjʉrʲɪj pʲɪˈtrovʲɪtɕ ɕːɪkɐˈtɕixʲɪn]; 9 June 1950 – 3 July 2003) was a Soviet and later Russian investigative journalist, writer, and liberal lawmaker in the Russian parliament. Shchekochikhin wrote and campaigned against the influence of organized crime and corruption. His last non-fiction book, Slaves of the KGB, was about people who worked as KGB informers.

As a journalist for the newspaper Novaya Gazeta (NG), Shchekochikhin investigated apartment bombings allegedly directed by the Russian secret services and the Three Whales Corruption Scandal which involved high-ranking FSB officers and was associated with money laundering through the Bank of New York. In the 1995 Russian legislative election he became a member of the State Duma. He was re-elected in the 1999 legislative election.

Shchekochikhin died suddenly on 3 July 2003 from a mysterious illness a few days before his scheduled departure to the United States, where he planned to meet with FBI investigators. His medical documents, according to NG, were either lost or destroyed by authorities. The symptoms of his illness fit a pattern of poisoning by radioactive materials and were similar to the symptoms of Nikolai Khokhlov, Roman Tsepov, and Alexander Litvinenko. According to Litvinenko and news reports, the death of Yuri Shchekochikhin was a politically motivated assassination.

Shchekochikhin was born in Kirovabad, Azerbaijan SSR in June 1950 and was of Azerbaijani origin.

Shchekochikhin graduated from the Journalism Department of Moscow State University in 1975. He worked as an investigative journalist at Komsomolskaya Pravda (1972–1980) and Literaturnaya Gazeta (1980–1996), and then as a deputy editor of the liberal newspaper Novaya Gazeta (from 1996). Beginning in the 1990s, he published many articles critical of the First and Second Chechen Wars, human rights abuses in the Russian army, state corruption, and other social issues.

In the summer of 1988, Shchekochikhin published an interview with a lieutenant colonel of the militia Aleksander Gurov, in which the existence of organized crime in the Soviet Union was first publicly stated. That brought fame to both Gurov (who became the head of the 6th Agency of the MVD of the USSR which struggled against organized crime) and Shchekochikhin.

Yuri Shchekochikhin began his political career in 1990, when he was elected as a representative to the Congress of People's Deputies. He was elected to the Russian State Duma from the liberal Yabloko party in 1995. He was a member of a Duma committee on the problems of corruption, and was a UN expert on the problems of organized crime. He was a vocal opponent of the First and Second Chechen Wars.

Since early 1995, he has been an author and host of an investigative journalism program called "Special Team" on ORT, Russian television's first channel (then owned by Boris Berezovsky). In October 1995, the heads of the channel closed the program. According to Shchekochikhin, the reason was an episode called "For Motherland! For Mafia!", which was devoted to the Chechen War and was unleashed, in his opinion, by the "leading banks of Russia".
