Gauge-invariant wave equations are obtained for massless fields in de Sitter space, with arbitrary, half-integer spin. Massless quanta with spins s=1/2, 3/2, ... carry a series of unitary, irreducible representations of the de Sitter group. The special gauge fields carry another series of unitary, irreducible representations, hence ghost fields as well as the Goldstone and the associated special gauge field are actually massive in de Sitter space. Fields (properly: potentials) do not admit chirality for spins other than 1/2, but the field strengths associated with spin 3/2 do admit duality.
