Nguyễn Nhạc (Vietnamese: [ŋwĩəŋ ɲâːk̚] chữ Hán: 阮岳, born 1743, died 1793) was the founder of the Tây Sơn dynasty, reigning from 1778 to 1788.

Nguyễn Nhạc and his brothers Nguyễn Lữ and Nguyễn Huệ, known as the Tây Sơn Brothers after their home district, ended the centuries-long civil war between the Trịnh Lords in northern Vietnam and the Nguyễn Lords in southern Vietnam, seizing control from these groups and the Lê dynasty. From 1778 to 1788, Nguyễn Nhạc proclaimed himself Emperor Thái Đức (Vietnamese: [tʰǎːj ɗɨ́k̚] chữ Hán: 泰德). In 1788, after his younger brother proclaimed himself Emperor Quang Trung, Nguyễn Nhạc resigned as Emperor and declared himself King of Tây Sơn.
