The Trumbullplex is a housing collective and showspace in the Woodbridge neighborhood of Detroit, Michigan, USA. It was created in 1993 when members of the collective established a nonprofit corporation and purchased the property, two Victorian houses on either side of a single-story art space.

The collective's mission statement asserts that they “want to create a positive environment for revolutionary change in which economic and social relationships are based on mutual aid and the absence of hierarchy.” It acts on the basis of consensus decision-making and serves as a home, theater, art gallery, infoshop, meeting space and temporary residence for traveling activists. The art space and infoshop are run on a donations-only basis, and members pay an equal portion of the costs involved in the property's upkeep each month.

The Trumbullplex has been an institution and hotbed of creative anarchism that has influenced those who have had residency and visited the Trumbullplex. The Trumbull Collective has a history of positive and unique exchange with activism happening internationally by bringing traveling plays, music, puppet shows, performance art, and workshops to the space. Members of the collective and surrounding community run the operations within the Theater and meeting space and also participate in alternative schools, such as the high school for teenage mothers, the Catherine Ferguson Academy and CFA farm, The Hub of Detroit (a cycling non-profit located in the city's Cass Corridor), to Detroit organizations promoting urban agriculture such as Earthworks, and to a variety of other causes and organizations. The Detroit IWW currently holds monthly General Membership Branch meetings in the theater for example.

The newest addition to the Trumbullplex, the Zine Library, is near completion as of June 2011 and the collective that runs it is set to appear at the 2011 Allied Media Conference in Detroit with a zine lounge. According to their wordpress and monthly calendar the zine library will be open a few days a week with regular hours and will house over 2,000 independently published books, pamphlets, and fanzines, many of which came from the now defunct Idle Kids infoshop in Cass Corridor.
