Washington has been awarded the National Hockey League's Winter Classic on Jan. 1, 2015.
The Capitals will host the game four years after they visited the Penguins at Heinz Field in Pittsburgh.
Capitals owner Ted Leonsis made the announcement at the team's fan convention Saturday.
"We are extremely excited to host the 2015 Bridgestone NHL Winter Classic and bring this great event to the D.C. area,” Leonsis said. “Our great fan base deserves to experience the magnificence of an outdoor game. We are thrilled to once again be part of this great event."
It was not immediately clear which team the Capitals will play, though there is speculation it will be the Philadelphia Flyers, who hosted the 2012 outdoor game.
"The excitement of the Bridgestone NHL Winter Classic continues to grow, and bringing the 2015 event to the D.C. area will write another chapter in the game's great history of entertainment," NHL Commissioner Gary Bettman said. "We are looking forward to being in Washington with the Capitals' great fans.
It was not clear where the game would be played. Nationals Park is the most logical place, though RFK Stadium and FedEx Field, which is in Landover, Md., could also be options.
It will be the seventh Winter Classic in league history, and weather could be an issue for the first one held south of the Mason-Dixon Line. The average high temperature on Jan. 1 in Washington is 7 degrees C, and the record was 20 in 2005.
