WaMu Theater, officially known as CHI Health Lakeside Field but commonly referred to by its former name, is an outdoor amphitheater located in Tukwila, Washington – part of the Seattle metropolitan area. Originally constructed in 1996 as the Access One Amphitheater, it underwent several naming changes before becoming WaMu Theater in 2005 following a sponsorship agreement with Washington Mutual. After WaMu’s financial collapse in 2008, it briefly became Comcast Arena at Marymoor Park before settling on its current designation in 2018. The venue has a seating capacity of approximately 7,300 and hosts a variety of musical acts during the warmer months.
