Abstract: A beverage holder for securing a beverage container to a support surface is provided. In one example, the beverage holder also insulates the beverage container. The beverage holder has a deformable base, which may be concave in shape. The base is constructed to act as a suction device to releasably attach the beverage holder to the support surface. A sidewall connects to the base to form a cylindrical void. Sidewall projections are spaced apart on the sidewall and extend into the void. The sidewall projections are constructed and arranged to frictionally engage the beverage container. In use, the beverage container is received into the void, and as the beverage container is pressed into the void, the deformable base suctionally couples to the support surface. The sidewall projections act to securely hold the beverage container in the void, while allowing air to escape.
