We give perturbative predictions for the distribution of the C-Parameter event shape variable in e+e− annihilation, including resummation of large logarithms in the two-jet (small-C) region, matched to next-to-leading order results. We also estimate the leading non-perturbative power correction and make a preliminary comparison with experimental data.
