Pete Sampras defeated Andre Agassi in the final, 6–3, 6–4, 5–7, 6–4 to win the men's singles tennis title at the 2002 US Open. It was his fifth US Open title (an Open Era record) and his all-time record-extending 14th major title overall. The final was a rematch of the 1990 and 1995 US Open finals, where Sampras won his first and seventh major titles respectively. It was Sampras' last professional appearance, though he did not officially declare his retirement until 2003. Sampras became the only man in the Open Era to win the final major he played.
Lleyton Hewitt was the defending champion, but lost to Agassi in the semifinals.
This marked the most recent occasion where eight different men appeared in the four major singles finals of a calendar year.
