  Using the natural extension of the notion of the generalized coherent states
the scalar and spinor ones for the de Sitter group SO(4,1) are constructed.
These systems of coherent states obey the de Sitter--invariant Klein-Gordon and
Dirac equations and correspond to the massive spin~0 and~1/2 particles over de
Sitter space. These coherent states are used for the construction of the
invariant scalar and spinor propagators over de Sitter space.
