贾科莫·莱奥帕尔迪（意大利语：Giacomo Taldegardo Francesco di Sales Saverio Pietro Leopardi，1798年6月29日－1837年6月14日），意大利诗人，散文家，哲学家，语言学家。他是意大利浪漫主义文学的重要代表，但他又认为所谓的“浪漫主义风格”并非独创，在古典作品比如荷马和维吉尔的诗歌中就有着浪漫主义的成分，因此又与其他浪漫主义作家略有分歧。他的早期作品如《致意大利》、《但丁纪念碑》充满了爱国热情，之后以《回忆》、《暴风雨后的宁静》为代表的田园诗和以《致西尔维娅》为代表的抒情诗被认为是继彼特拉克之后最有魅力的一批诗作，但他的生长环境和体弱多病又使他有着强烈的悲观主义，他将悲观主义哲学融入了以《无限》、《一个亚洲游牧人的夜歌》为代表的诗歌和《道德小品》、《杂记》为代表的散文中，使作品具有了一种特殊的忧伤情调。

Giacomo Taldegardo Francesco di Sales Saverio Pietro Leopardi (Italian: [ˈdʒaːkomo leoˈpardi]; June 29, 1798 – June 14, 1837) was an Italian poet, philosopher, essayist and philologist. He is widely acknowledged to be one of the most radical and challenging thinkers of the 19th century. Although he lived in a secluded town in the ultra-conservative Papal States, he came in touch with the main thoughts of the Enlightenment, and, by his own literary evolution, created a remarkable and renowned poetic work, related to the Romantic era. The extraordinary lyrical quality of his poetry made him a central protagonist in the European and international literary and cultural landscape.
