Abstract: A portable stage having at least a transport configuration and a deployed configuration is disclosed. The portable stage includes a chassis having wheels rotatably attached thereto and a main floor panel attached to the chassis. First and second deployable floor panels are pivotally attached to the main floor panel, and a deployable canopy is attached to the chassis. The deployable canopy is stored between the first and second floor panels when the portable stage is in its transport configuration. When the stage is deployed, the main floor panel, first floor panel and second floor panel form a main stage, and the canopy is large enough to cover the main stage.
