Ansan Wa~ Stadium () is a multi-purpose stadium in Ansan, Gyeonggi-do, South Korea. It's currently served as home stadium for Ansan Greeners FC. The stadium was opened in 2007 and has a capacity of 35,000 people. It is used mostly for football matches and athletics. It is located next to Gojan Station on Seoul Subway Line 4.
While under construction it was known as "Ansan Stadium". After the public subscription during the construction, the formal name "Ansan Wa~ Stadium" was selected. "Wa" means harmonious cheering and the wave notation (~) represents the extension of that sound. 2013 HSBC Asian Five Nations rugby union game was held in the stadium.
