Juan Martín del Potro (born 23 September 1988), nicknamed Delpo , is an Argentine professional tennis player who is currently ranked world No. 4 in men's singles by the Association of Tennis Professionals (ATP).

His biggest achievement has been winning the 2009 US Open, defeating Rafael Nadal in the semifinal and 5-time defending champion Roger Federer in the final. He was the first to defeat both Federer and Nadal during the same major and was the only man outside the Big Four to win a major between the 2005 French Open and the 2013 US Open, a span of 35 tournaments. He is also the second Argentine and the fifth-youngest man to win the US Open in the Open Era. Other career highlights include reaching the 2018 US Open final, winning the bronze medal in men's singles at the 2012 London Olympics, the silver medal at the 2016 Rio Olympics, the Indian Wells Masters in 2018.

He again returned to the ATP World Tour in February 2016 after a long injury-induced absence. At the 2016 Summer Olympics he discovered a huge vein of form, defeating World No. 1 Novak Djokovic in straight sets in the first round and No. 3 Rafael Nadal in the semi-finals, claiming silver after falling in the final to No. 2 Andy Murray in four attritional sets. Only weeks later, Murray and del Potro met again in the Davis Cup semi-final in Glasgow, with del Potro emerging victorious in 5 sets. He then led Argentina to their first ever Davis Cup victory by defeating Croatia's Marin Čilić in the final in Zagreb. He reached his first major semi-final since 2013 by defeating Roger Federer in the quarter-finals of the 2017 US Open. In 2018, he won his first Masters 1000 title at the Indian Wells Masters, defeating defending champion and World No. 1 Roger Federer in the final. After reaching the semi-finals of the 2018 French Open, he again matched his career high of No. 4. Finally, in August, he achieved the World No. 3 ranking for the very first time. At the 2018 US Open, he reached his second Grand Slam final.
