Tamás Darnyi (born 3 June 1967 in Budapest) is a Hungarian retired male swimmer.

[1] He won four gold medals at two Olympic Games (1988 and 1992) and was unbeaten in the individual medley events from 1985 until his retirement in 1993.

Possibly one of the greatest medley swimmers of all time, Tamás Darnyi dominated his speciality between 1985 and 1993.

A teen talent, Darnyi might have competed at the 1984 Olympics, but both the Eastern European boycott and a personal accident prevented this.

After his final European title in 1993 (400 medley), he retired and managed a Budapest sports school.
