Santiago Giraldo Salazar (born 27 November 1987) is a Colombian male tennis player from Pereira in Colombia. He plays on the ATP tour and represents Colombia in the Davis Cup competition. Giraldo's career-high singles ranking is World No. 39.
Since turning professional in 2006, Santiago Giraldo has competed in lower events at Buenos Aires, Bogotá and Asunción. He reached the final at Bogotá in October 2007 but he lost out in straight sets. Giraldo reached his first Grand Slam main draw at the 2007 French Open, where he lost to Novak Djoković.
At the 2010 Internazionali BNL d'Italia in Rome, a Masters 1000 event, he produced a heavy ground game to crush down 12th seed Juan Carlos Ferrero 6–0, 6–3 in the first round, followed by a 6–3, 6–2 win over Michaël Llodra in the second round. However his run was ended at the hands of World No. 10 and 7th seed Jo-Wilfried Tsonga 3–6, 4–6 in the third round.
Giraldo is known for consistently taking huge cuts at the ball, flattening out every forehand and backhand possible when he is able to get a firm grip on the ball. However, such a style of play evidently generates a higher chance of unforced errors. Also, Giraldo can be seen as one the best service returners, if not the best.
