Juhan Parts (born 27 August 1966 in Tallinn) is a former Prime Minister of Estonia, and former chairman of the Res Publica Party. Since 5 April 2007 he is the Minister of Economy and Communication in Andrus Ansip's second government. Juhan Parts is a member of the Union of Pro Patria and Res Publica party.

Juhan Parts completed Gustavus Adolphus Grammar School in Tallinn (then Tallinn Secondary School No. 1). Afterwards, he studied law at the University of Tartu in Tartu, Estonia.

After completing his university education, Parts instantly joined the Ministry of Justice. He soon became known as a young, dynamic figure who wanted to push for reforms. As an ally of Deputy Minister Mihkel Oviir, he was appointed Auditor General in the spring of 1998. He held this office until 2002. From this virtually unimpeachable office, unique in the Estonian Constitution, he frequently criticised the government and became somewhat of a popular figure in Estonian politics.
