2013 U.S. National Indoor Tennis Championships – Women's singles

Sofia Arvidsson was the defending champion, but lost to Marina Erakovic in the second round in a replay of the previous final. Erakovic made it to the finals again, this year defeating Sabine Lisicki 6–1 in the first set after Lisicki retired due to illness before the start of the second set. This was Erakovic's first WTA tour level title and the first New Zealander to win the WTA title since Belinda Cordwell in 1989.
