Disclosed is an insulated beverage dispenser having a generally cube-shaped insulated body with an interior chamber, an open top, and an outlet adjacent a bottom of the interior chamber. It includes a removable closure member for the outlet and an insulated top hingedly connected to the body to close the open top. A guideway is located on a front outer surface of the body generally adjacent the open top and is sized and positioned to receive a securement strap extended across the body without interference with opening the top. The closure member can be a liquid dispensing valve and/or a plug. An interior surface of the lid may include a recess for receiving a spare closure member for the outlet.
