2017 US Open Series
In tennis, the 2017 US Open Series was the fourteenth edition of the US Open Series, which comprised a group of hard court tournaments that started on July 24, 2017 in Atlanta and concluded in Connecticut for the women and in Winston-Salem for the men on August 26, 2017. This edition consisted of three separate men's tournaments and three women's tournaments, with the Western & Southern Open hosting both a men's and women's event.

Discontinuation of the Bonus Challenge
The 2017 US Open Series is the first edition of the series not to feature the Bonus Challenge. In previous years, players had been eligible for additional prize money, based on a combination of their finish in the series and their finish in the US Open itself, with the maximum amount of money being awarded to a player who won both.Tournament schedule
