We examine interference phenomena involving entangled pairs of quantum coherent states. Two-coherent-state interferometry, which can involve macroscopic numbers of photons, is shown to share several characteristics of two-particle quantum interferometry in such a macroscopic limit. These include the complementarity between one-system and two-system interference visibilities in the extreme cases of product and maximally entangled quantum states, and the violation of a Bell-type inequality.
