In tennis, the ninth edition of the US Open Series (known as Emirates Airline US Open Series for sponsorships reasons), included twelve hard court tournaments that started on July 9, 2012 in Stanford and concluded in Winston-Salem for the men and in New Haven for the women on August 26, 2012. This edition scheduled four separate men's tournaments and four women's tournaments – the Citi Open and the Western & Southern Open hosted both a men's and women's event. The series was headlined by two ATP World Tour Masters 1000 and two WTA Premier 5 events. The series winners were Novak Djokovic and Petra Kvitová.

In order to be included in the standings and subsequently the bonus prize money, a player needed to have countable results from two different tournaments. Players who finished in the top three in the series could have earned up to $1 million in extra prize money at the US Open. Roger Federer received the largest US Open pay day of $2.4 million in 2007 after capturing the title in both the US Open Series and the US Open championship.
