  For three dimensional N=6 superconformal field theories we compute one-loop
scattering amplitudes for any number of external particles. We focus on a
particular subsector of N=2 invariant superamplitudes for which the ordinary
perturbative evaluation becomes very easy. The result we obtain is in general
non-vanishing. For six external particles our findings are sufficient for
determining the complete expression of the N=6 superamplitude at this order. We
discuss the symmetries of the result and its anomalous variation under
superconformal generators.
