Bob Bradley (born March 3, 1958 in Montclair, New Jersey) is a soccer coach, the current head coach of the MetroStars of Major League Soccer, and the all-time winningest coach in league history.

Bradley's coaching career started in 1981, when he was named the head coach of Ohio University at the age of 22. He was hired away by University of Virginia coach Bruce Arena and spent two years as his assistant, before taking the head job at his alma mater, Princeton. Bradley coached the Tigers from 1984 to 1995, winning two Ivy League titles and reaching the NCAA Final Four in 1993.

In 1996, Bradley became Arena's assistant once again, this time with DC United of the newly-formed Major League Soccer. After two seasons there, he became the first head coach of the expansion Chicago Fire, and promptly led them to the MLS Cup and US Open Cup double in 1998, being named MLS Coach of the Year in the process. He would win another Open Cup in 2000.

After the 2002 MLS season, Bradley resigned as coach of the Fire and took the reins of his home state team, the MetroStars (ironically, he was up for the Metro job three times in 1996 and 1997). Although he hasn't been able to win any silverware yet, he has the perennial underachivers headed in the right direction: they made their first cup final in club history in 2003.

Bradley is widely tipped to succeed Arena with the US national team. A number of his relatives are involved in sports as well; his brother Scott played baseball for the Seattle Mariners in the 1980s, and his other brother Jeff is a writer for ESPN The Magazine . Bradley's son, Michael, was drafted by the MetroStars in the 2004 MLS SuperDraft, but did not see any playing time in his first season with the team.
