  Inelastic neutron scattering experiments were performed on single crystals of
the heavy-fermion compound CeIn$_{3}$ for temperatures below and above the
N\'eel temperature, $T_N$. In the antiferromagnetically ordered phase,
well-defined spin-wave excitations with a bandwidth of 2 meV are observed. The
spin waves coexist with quasielastic (QE) Kondo-type spin-fluctuations and
broadened crystal-field (CF) excitations below $T_N$. Above $T_N$, only the QE
and CF excitations persist, with a weak temperature dependence.
