Oleksandr Turchynov was born in Dnipropetrovsk. He graduated from the Dnipropetrovsk Metallurgical Institute in 1986, after which he worked at Kryvorizhstal. From 1987 to 1990, he served as head of the agitation and propaganda division of the Dnipropetrovsk Oblast Komsomol (Communist Youth League) Committee, which was led by Sergei Tigipko. Tigipko and Turchynov became political patrons of Leonid Kuchma, then head of Dnipropetrovsk-based Pivdenmash missile manufacturer. Kuchma and his entire team, including Tigipko and Turchynov moved to Kiev in 1992, after Kuchma was appointed Prime Minister. In 1993 Turchynov was formally appointed an advisor on economic issues to Prime Minister Kuchma.
Turchynov is an old ally of Yulia Tymoshenko, another prominent Ukrainian political figure from Dnipropetrovsk. They used to have a common business in Dnipropetrovsk. In December 1993, Turchynov co-founded and became Vice President of Ukrainian Union of Industrialist and Entrepreneurs. In 1994 he created the political party Hromada together with Pavlo Lazarenko, a business ally of Tymoshenko. Turchynov was also director of the Economic Reforms Institute from January 1994 to March 1998 and was head of the Ukrainian National Academy of Sciences’ Laboratory of Shadow Economy Research.
In 1998, he was elected to parliament as a member of Hromada but after the scandal around Lazarenko, he left the faction and party (during May 1999) together with Yulia Tymoshenko’s All-Ukrainian Union "Fatherland". He was re-elected to parliament in 2002 and 2006 as part of the BYuT.
On 4 February 2005, Turchynov was appointed and served as the first‐ever civilian head of the Security Service of Ukraine (SBU). In February 2006 state prosecutors opened a criminal case against Turchynov and his SBU deputy Andriy Kozhemyakin for destroying a file about FBI Ten Most Wanted FugitiveSemyon Mogilevich from the SBU archive. The case was dismissed four months later.
In the spring of 2008 he was the Yulia Tymoshenko Bloc and the Our Ukraine–People's Self-Defense Bloc candidate for the Mayor of Kiev election he placed second at the election with 218,600 votes (19.13% of total vote).
In December 2009 during the 2010 Ukrainian presidential election-campaign Turchynov accused PresidentViktor Yushchenko and opposition leader Viktor Yanukovych of coordinating their actions in their attempts to topple the Second Tymoshenko Government.
On March 4, 2010, after the fall of the second Tymoshenko Government, former Prime Minister Yulia Tymoshenko resigned from that post on March 4, 2010 and Turchynov was empowered to fulfill the Prime Minister's duties until a new government was formed.

On February 22, 2014 he was elected as speaker of Verkhovna Rada and, in addition, Turchynov was designated as acting President of Ukraine and acting Prime Minister of Ukraine following the impeachment of Viktor Yanukovych.
In August 2007, Turchynov replied to the accusation that his stance on same-sex marriage is typically conservative, "I do not agree. If a man has normal views, then you label him a conservative, but those who use drugs or promote sodomy – you label them a progressive person. All of these are perversions.”
In 2004 Turchynov published a book "Illusion of fear". In 2005 he also wrote a script to the same name movie that is based on the book. The movie was released in Ukraine in September 2008 and was the 2008 Ukrainian submissions for the Academy Award for Best Foreign Language Film.
