2018 US Open – Women's doubles

Ashleigh Barty and CoCo Vandeweghe defeated Tímea Babos and Kristina Mladenovic in the final, 3–6, 7–6(7–2), 7–6(8–6) to win the women's doubles tennis title at the 2018 US Open. They saved three championship points en route to the title.

Babos, Ekaterina Makarova, and Kateřina Siniaková were in contention for the WTA No. 1 doubles ranking. Babos retained the ranking at the end of the tournament after Makarova failed to reach the final and Siniaková failed to claim the title.
