The 2017–18 USC Trojans women's basketball team represented the University of Southern California during the 2017–18 NCAA Division I women's basketball season.

The Trojans, led by first year head coach, 6th overall Mark Trakh, played their home games at the Galen Center and were members of the Pac-12 Conference.

They would have clinched the automatic berth to the 2018 Women's National Invitation Tournament, but declined to participate, despite being the highest-ranked non-NCAA team in the Pac-12.

They lost in the first round Pac-12 women's basketball tournament to California.
