Abstract: This note concerns the entropy of the Ehrenfest urn model. Both Boltzmann and Gibbs entropies are discussed. It is shown that they agree at equilibrium. The Boltzmann entropy shows fluctuations in time while the Gibbs entropy is proved to increase monotonically to its maximum (equilibrium) value. The concepts of equilibrium associated with the two points of view are compared.
