Alejandro Falla Ramírez (Spanish pronunciation: [aleˈxandɾo ˈfaʎa raˈmiɾes];[1] born 14 November 1983) is a retired professional male tennis player from Colombia.

The Colombian became the first player from his country to break into the top 100 of the ATP rankings since Mauricio Hadad in 1996.

Falla almost caused a sensation in the first round of Wimbledon in 2010, winning the first two sets against defending champion Roger Federer and serving for the match at 5–4 in the fourth set (he was three points away from winning), before Federer eventually won 5–7, 4–6, 6–4, 7–6, 6–0.

Falla reached the fourth round, where he lost to the unseeded Juan Ignacio Chela.

In the 2014 Gerry Weber Open in Halle, Falla rallied to beat 2011 champion Philipp Kohlschreiber 5–7, 7–6 (5), 6–4 to become the first Colombian to reach the final of a grass-court tournament.
