A portable deployable table is a device that may be easily mounted to and removed from a surface or structure. The device includes a housing with at least one telescopic arm fixed within the housing. A table frame and a planar table top are hingedly connected to the at least one telescopic arm and may be deployed after being extended from within the housing. The table frame and the planar table top are contained within the housing when the device is not in use. At least one adjustable mounting brace is connected to the exterior of the housing, allowing the housing to be mounted to a surface or structure and fixed in place. The housing may be closed via a housing lid that covers the interior of the housing.
