ČEZ stadion Kladno, Indoor ice rink in Kladno, Czech Republic.

ČEZ stadion Kladno is an indoor ice hockey arena in Kladno, home of Rytíři Kladno, with a capacity of 5,200 seats, of which 1,500 are standing places. The ice surface, its machinery room and boiler room were rebuilt in 2001–2002, and the arena has had a new roof since 2022.

The arena opened in 1949 and its roof was completed in 1959. A planned new hall backed by Otakar Černý and Jaromír Jágr senior was abandoned after the region withdrew support under governor David Rath. The stadium was renamed ČEZ stadion in 2012, and a 300-million-crown reconstruction began in 2013.

The team is named Rytíři Kladno, Knights of Kladno, and plays its home games here. The club's presidency has been linked to Jaromír Jágr senior, father of the hockey player Jaromír Jágr, and to manager Otakar Černý, who pushed a planned new hall.

The arena is owned by the city of Kladno and seats 5,200 people, of whom 1,500 are standing places. During the 2021–2022 roof reconstruction, Rytíři Kladno played their home games in the Rocknet aréna in Chomutov, so check which venue is hosting before travelling.

The city of Kladno sought 140 million crowns from European Union funds for a planned new 7,000-seat hall, but the project stalled after David Rath became regional governor and the region withdrew support. The existing stadium was instead renamed ČEZ stadion in 2012.
