Dang Thai Son (born 1958 in Hanoi Vietnam) is a noted classical pianist. He is best known for being the first Asian pianist to win the prestigious International Frederick Chopin Piano Competition in 1980. Dang Thai Son's glory, however, is marred by controversial elimination of Ivo Pogorelić in the third round, which caused the Argentine pianist Martha Argerich to quit the jury in protest.

The controversy did not deter Dang Thai Son, however, and he went on to a distinguished career as a concert pianist. He remains one of the world's foremost Chopin interpreters.
