There is increasing evidence that the universe may have a small cosmological constant. We suggest a scheme for naturally generating a small cosmological constant. Our idea requires the presence of a discrete accidental symmetry which is spontaneously broken by vacuum expectation values of the fields, and explicitly broken by high dimensional operators in the Lagrangian.
