2002 US Open – Women's singles

Serena Williams defeated the two-time defending champion, her sister Venus Williams, in a rematch of the previous year's final, 6–4, 6–3 to win the women's singles tennis title at the 2002 US Open. It was her second US Open singles title, her fourth major singles title overall, the third component of her first "Serena Slam" (a non-calendar year Grand Slam and career Grand Slam), and her second consecutive major title won without losing a set.

This marked the final major appearance for four-time major champion and former world No. 1 Arantxa Sánchez Vicario, who lost to Marion Bartoli in the first round. It was also the final US Open appearance of two-time champion Monica Seles, who lost to Venus Williams in the quarterfinals. It was also the first major appearance for future world No. 1 and three-time major finalist Dinara Safina, who lost in the second round to Serena Williams.
