We compute the physical graviton two-point function in de Sitter spacetime
with three-sphere spatial sections. We demonstrate that the large-distance
growth present in the corresponding two-point function in spatially flat de
Sitter spacetime is absent. We verify that our two-point function agrees with
that in Minkowski spacetime in the zero cosmological constant limit.
