Đặng Thái Sơn is a Vietnamese-Canadian classical pianist. In 1980, he won the X International Chopin Piano Competition in Warsaw, becoming the first pianist from Asia to do so. He has received particular acclaim for the sonority and poetry in his interpretations of Chopin and the French repertoire.

The X International Chopin Piano Competition was held from 1 to 20 October 1980 in Warsaw. Đặng Thái Sơn, who in the final played with an orchestra for the first time in his life, won first prize, becoming the first pianist from Asia to do so. The elimination of Ivo Pogorelić after the third stage was a great source of controversy.
