Capitol Hill Arts Center, also known by its acronym CHAC (pronounced "shack"), was a performing arts center located in the Capitol Hill neighborhood of Seattle, Washington.
CHAC operated two performance spaces in the building, most widely known for its theatre.
CHAC was acknowledged as producing some of the most exciting theatre in Seattle:[1] from Bertolt Brecht's The Resistible Rise of Arturo Ui and Clifford Odets' Waiting for Lefty to the Pacific Northwest premiere of Dario Fo's Archangels Don't Play Pinball.
On the evening of Friday, March 24, 2006, CHAC was the venue of a zombie-themed rave called "Better Off Undead".
Attendees of an afterparty after that rave were the victims of the Capitol Hill massacre.
