Duje Bonačić (10 April 1929 – 24 January 2020) was a Croatian rower who won a gold medal representing Yugoslavia in the coxless four event at the 1952 Summer Olympics.
He graduated in natural sciences in Zagreb, and took up rowing to build muscles, as he weighed only 56 kg with a height of 183 cm at the time.
After retiring from competitions he worked as a professor of geography, meteorology and oceanography at maritime schools and also served as a coach and referee in rowing and sailing.
[2] After the death of Željko Čajkovski on 11 November 2016, he became the oldest Croatian Olympic medal winner.
