We propose a massless self-interacting non-minimally coupled scalar field as a mechanism for stabilizing the size of the extra dimension in the Randall-Sundrum I scenario. We obtain a stable minimum of the effective potential, which yields the compactification scale, and give an analytical expression for the compactification radius.
