A trailer canopy system for providing an area adjacent a trailer that is protected from inclement weather includes a canopy that is extendable from a side of a trailer. The canopy protects an area under the canopy from inclement weather when the canopy is extended from the trailer. A support bar is coupled to a free edge of the canopy positioned opposite of the trailer. Each of a pair of bracing assemblies is pivotally coupled to each of the support bar and the trailer. Each of the bracing assemblies pivots between a stored position and a deployed position. The stored position is defined when each of the bracing assemblies is positioned adjacent the side of the trailer. The deployed positioned is defined when each of the bracing assemblies extends away from the trailer and supports the support bar and the canopy over a ground surface.
