The Washington DC Open (also known as the Washington Open and DC Open), currently called the Mubadala Citi DC Open for sponsorship reasons, is an annual professional outdoor hardcourt tennis tournament played at the William H.G. FitzGerald Tennis Center in Rock Creek Park in Washington, D.C. The event is categorized as an ATP 500 event on the ATP Tour and a WTA 500 event on the WTA Tour and is the only combined 500 event in the world.The tournament is owned and managed by Mark Ein in partnership with IMG.
Organized annually in the summer schedule of events on North American hardcourts leading up to the US Open, the Washington Open was first held in 1969 as the Washington Star International. It was held on clay courts until 1986, when the surface was changed to hardcourts. In 2011, the event expanded to include its first women's tournament, a WTA International (now WTA 250) competition held in a separate venue in College Park, Maryland. The following year, the men's and women's events were consolidated at the Washington venue.
In 2023, the WTA 500-level Silicon Valley Classic was discontinued and merged with the Washington Open, forming the first joint-500-level event on the ATP and WTA tours.
