An umbrella stand includes means defining a cavity, a mast receiving means operatively associated with the cavity-defining means, a bladder received within the cavity and comprised of a material which will retain ballast, and ballast contained within the bladder. When an umbrella mast is inserted into the mast receiving means and the umbrella is raised, the ballast weighs down the cavity-defining means so as to maintain the umbrella in a generally upright condition.
