Let G be a finite group. By a rational coefficient system for G we mean a contravariant functor from the category of canonical orbits of G and G- maps into the category of Q-vector spaces. In this paper we study injective objects in the category or rational coefficient systems for G. In particular, we give a complete description of injective envelopes.
