Melchior Klesl (19 February 1552 – 18 September 1630) was an Austrian statesman and cardinal of the Roman Catholic Church during the time of the Counter-Reformation. He was minister-favourite of King and Emperor Matthias (1609-1618) and a leading advocate for peace between the empire's different confessional leagues before the Thirty Years' War.

Klesl was appointed Bishop of Vienna in 1602 and elevated to cardinal in December.
