Naomi Osaka defeated Serena Williams in the final, 6–2, 6–4, to win the Women's Singles tennis title at the 2018 US Open. At the age of 20 and seeded 20th, Osaka became the first Japanese competitor to win a Grand Slam singles title and the youngest US Open champion since Maria Sharapova in 2006. In virtue of her victory, Osaka also made the top 10 for the first time, debuting at No. 7. Osaka dropped just one set the entire tournament, to Aryna Sabalenka in the fourth round.

Sloane Stephens was the defending champion, but lost to Anastasija Sevastova in the quarterfinals. Simona Halep's first-round loss to Kaia Kanepi marked the first time in the Open Era that the top seed lost in the first round of the women's singles of the US Open. Despite her loss, Halep retained the WTA No. 1 singles ranking at the end of the tournament.

The losses of Halep in the first round and Caroline Wozniacki in the second round marked the first time that neither of the top two seeds advanced past the second round of the US Open women's singles event, and the second time this happened at any Grand Slam event in the Open Era (following the 2014 French Open).

Serena Williams was attempting to equal Margaret Court's all-time record of 24 Grand Slam singles titles. Williams was also attempting to set a new Open Era record by winning a seventh US Open singles title. She remains tied with Chris Evert at six.

This was also the final Grand Slam appearance for former World No. 2, 2012 Wimbledon finalist and 2015 WTA Finals champion Agnieszka Radwańska, who was unseeded for the first time since 2007 Wimbledon Championships, she lost in the first round to Tatjana Maria.

This was also the final Grand Slam singles appearance for former World No. 5 and 2015 French Open finalist Lucie Šafářová. She would retire after participating in the doubles tournament at the 2019 French Open. She lost in the second round to Ashleigh Barty.
