We show that p-forms on AdS(2p+1) describe both singletons and massless par
ticles. On the 2p-dimensional boundary the singleton p-form Lagrangian redu
ces to the conformally invariant functional integral F-2. All the represent
ations, singletons as well as massless, are zero center modules and involve
a vacuum mode. Two- and three-form singleton fields are required by supers
ymmetry in AdS(5) and AdS(7) supergravity, respectively.
