克劳迪奥·乔瓦尼·安东尼奥·蒙特威尔第（意大利语：Claudio Giovanni Antonio Monteverdi，1567年5月15日－1643年11月29日），意大利作曲家、制琴师。出生于意大利北部克雷莫纳市的他，从小就接触圣歌等音乐教育，并在未成年即有作品面世。16世纪末，受到贡扎加家族支助下，他与宫廷歌手合作，出版了牧歌等普罗歌曲。而《奥菲欧》可算是蒙特威尔第最出名的歌剧。

蒙特威尔第被认为是古典音乐史上一位划时代的人物，他的牧歌创作是这一文艺复兴时期音乐体裁的巅峰，而他的歌剧创作则是这种体裁的奠基之作。他是巴洛克音乐的早期代表。

Claudio Giovanni Antonio Monteverdi (Italian: [ˈklaudjo monteˈverdi]; 15 May 1567 (baptized) – 29 November 1643) was an Italian composer, gambist, singer and Roman Catholic priest.

Monteverdi's work, often regarded as revolutionary, marked the change from the Renaissance style of music to that of the Baroque period. He developed two styles of composition – the heritage of Renaissance polyphony and the new basso continuo technique of the Baroque. Monteverdi wrote one of the earliest operas, L'Orfeo, a novel work that is the earliest surviving opera still regularly performed. He is widely recognized as an inventive composer who enjoyed considerable fame in his lifetime.
