Albert Costa Casals (; born 25 June 1975) is a Spanish former professional tennis player. He is best remembered for winning the men's singles title at the French Open in 2002.
In 1995, Costa won his first top-level singles title at Kitzbühel, defeating "King of Clay", Thomas Muster, in a five set final, beating Muster "with a mix of good ground shots, well-judged drop and slice winners and simple stamina in long baseline duels". It was Muster's first of 2 losses on clay in 1995. Costa ended Muster's streak of 40 consecutive clay match wins and his 11 consecutive final wins. Costa won three further titles in 1996. In 1997, he claimed two singles titles and was part of the Spanish team that won the World Team Cup. In 1998, he won another two singles titles, including the Tennis Masters Series event in Hamburg Masters. He won three more titles in 1999.
In 2000, Costa was part of the Spanish team that won its first Davis Cup. Although he was eliminated in the first round in men's singles, he also won a bronze medal in the men's doubles at the 2000 Olympic Games in Sydney, partnering Álex Corretja.
At the 2002 French Open, Costa had not won a tour title since 1999 and was seeded 20th, he defeated Richard Gasquet, Nikolay Davydenko and Andrea Gaudenzi to reach the fourth round, where he defeated two time defending-champion and former world No. 1 Gustavo Kuerten in straight sets. Costa followed up with a five-set victory over Argentina's Guillermo Cañas in the quarterfinals. He then defeated fellow-Spaniard, former world No. 2 and long-time friend Àlex Corretja in a four-set semifinal. In the final, Costa came up against another Spaniard, future world No. 1, Juan Carlos Ferrero. Ferrero had been in fine form in the run-up to the event and most observers considered him to be the heavy favourite going into the final. But Costa won in four sets to claim his first Grand Slam title. Costa destroyed Ferrero, who could only win nine points during Costa's service games in the first 2 sets. "It was the best match of my life" said Costa afterwards. The win propelled him to his career-high singles ranking of World No. 6 in July 2002.
Coming into the 2003 French Open as the defending champion, Albert Costa spent a total of 21 hours and 15 minutes on court, winning four five-setters before eventually being knocked out in a semifinal by Ferrero (who went on to win the title).

Over the course of his career, Costa won 12 top-level singles titles. In 2005, he claimed his first ATP tour doubles title in Doha, partnering with Rafael Nadal.
