The Wonder Ballroom is a music venue located in northeast Portland, Oregon. Prior to opening in 2004, the building (originally constructed in 1914) was occupied by the Ancient Order of Hibernians, the Catholic Youth Organization, the Portland Boxing School, the American Legion Organization, and a community center eventually known as the Collins Center. In 2006, the building was listed on the National Register of Historic Places as the Hibernian Hall for its "historic and architectural significance".
