Brian Richard Baker (born April 30, 1985) is an American retired professional tennis player from Nashville, Tennessee.

In 2003, he reached the boys' singles final of the French Open after beating Marcos Baghdatis in the quarterfinals and Jo-Wilfried Tsonga in the semifinals.

Baker's biggest win of his fledgling career occurred in August 2005, when he scored an upset victory over ninth-seeded Gastón Gaudio in the 2005 US Open.

He secured a straight-set victory over Rui Machado in his first-round match before dismissing Jarkko Nieminen, also in straight sets, to progress to the third round.
