Abstract: An adjustable receptacle holder for securely supporting a receptacle within a vehicle comprises a telescopic base member and a cylindrical holding member. The telescopic base member is removably inserted into a cup holder of the vehicle. The telescopic base member is configured to vertically extend and retract to suitably position the cylindrical holding member. The cylindrical holding member is rotatably attached to the telescopic base member and comprises sidewalls and an opening. The opening is configured in the sidewall of the cylindrical holding member to accommodate a handle of the receptacle. The cylindrical holding member is divided into four sections, each section comprising a ribbed guide rail configured on the base of the cylindrical holding member for radial adjustments to secure receptacles of varied base dimensions. Further, release tabs are provided on an exterior surface of each of the four sections to release the secured receptacle.
