Carlo Rizzi (born 19 July 1960, Milan, Italy) is an Italian conductor.
Rizzi studied music at the Milan Conservatory. He later was a conducting student of Vladimir Delman, in Bologna, and with Franco Ferrara in Siena. His opera conducting debut was in 1982, with Donizetti's L'ajo nell'imbarazzo. In 1985, he won the first Toscanini Conductor's Competition in Parma.
Rizzi made his UK conducting debut at the 1988 Buxton Festival with Donizetti's Torquato Tasso, and subsequently conducted productions at the Royal Opera House, Covent Garden and Opera North. In August 1992, he became music director of Welsh National Opera (WNO), and served in the post through 2001. He learned to speak Welsh during his tenure. In 2004, following the sudden resignation of Tugan Sokhiev, Rizzi's successor at WNO, Rizzi returned as WNO's music director, which was expected to be initially for a period of 2 years. He remained in the post through 2007.
Rizzi's recordings include an English-language version of Leoš Janáček's Káťa Kabanová (Chandos), and a DVD set of La Traviata (Deutsche Grammophon).
