David Marrero Santana (; born 8 April 1980) is a Spanish former professional tennis player. He has a career-high ATP singles ranking of No. 143 achieved on 8 February 2010 and a doubles ranking of world No. 5 on 11 November 2013. Marrero won 14 doubles titles

Professional career 2000–2007 Marrero earned his first world ranking late in 2000 as a 20-year-old, but he spent only a few weeks inside the top-500 until early 2005. By late 2005, he had made it into the top-300, but faded over the next year to close out 2006 outside the top-400. In the middle of 2007, he again inched into the top-300, but faded again to close out 2007 at No. 362.

2008: Maiden Challenger singles final As a qualifier, Marrero reached the final of a Challenger in Chile in January, losing to No. 132 Rubén Ramírez Hidalgo after upsetting No. 272 Sebastián Decoud, No. 187 Adrián García and No. 111 Nicolás Lapentti. This result brought him back into the top 300 at World No. 289. The very next week he gained revenge over Ramirez-Hidalgo to qualify into an ATP stop in Chile, where he again beat García before losing to No. 104 Fabio Fognini in the second round. In February, Marrero scored another upset, defeating World No. 114 Máximo González.

2009–2013: ATP Tour Finals, World No. 5 in doubles Marrero reached his career-high singles ranking of World No. 143 on 8 February 2010 and career-high ranking of World No. 5 in doubles on 11 November 2013 after winning the ATP World Tour Finals with Fernando Verdasco defeating the Bryan brothers.

2022–2025: Retirement, Continued Challenger/ITF play Marrero announced his retirement at the 2022 Barcelona Open Banc Sabadell, but continued to play on the Challenger and ITF circuits.

In October 2024, he won an ITF doubles tournament playing with Sergi Fita Juan.

Match fixing controversy In January 2016, Marrero was featured in a New York Times article about his suspected match-fixing at the Australian Open.

ITIA 31-month tour ban In November 2025, it was announced that Marrero was given a 31-month ban by the International Tennis Integrity Association (ITIA) that started on 21 October 2025 and would finish on 20 May 2028 after accepting sanctions for violating the Tennis Anti-Corruption Program wildcard rules. He admitted to four instances between 2022-23 of paying and offering to pay for wildcards for himself and/or a doubles partner.
