Emilio D'Aquino (born 26 March 1982) is a triathlete from Italy, who competed at the 2008 Summer Olympics in Beijing.

As a member of CS Carabinieri, D'Aquino repeated his success in triathlon by winning ten Italian titles, including four in the Olympic distance.

He was also selected for the Italian team in triathlon, and guaranteed his qualifying berth for the 2008 Summer Olympics in Beijing, along with his teammate Daniel Fontana, a former competitor from Argentina at the previous games in Athens.

D'Aquino continued to participate in European and World championships at the peak of his career, despite fulfilling his economics degree.

In December 2010, he decided to retire from triathlon to focus on his professional business career in the financial sector.
