Abstract: An adjustable container holder for holding cups, cans, glasses, bottles, and the like has a structural base with a cylindrical sidewall bearing a slot or slots for an adjustable strap. The strap passes through a slot from the outer side of the base to the inner side, wraps around the inner side and any container placed in the base, and passes through the same slot, or a closely adjacent slot, from the inner side to the outer side of the base where an adjustable attachment secures the strap. With both ends of the strap secured under tension and wrapped around a container, the container of variable size is captured in the structural base along all or a substantial portion of the container periphery.
