AB We report on very strong evidence of the occurrence of power terms inα^MOM(p), the QCD running coupling constant in the ^MOM scheme, by analyzingnon-perturbative measurements from the lattice three-gluon vertex between 2.0 and10.0GeV at zero flavor. While putting forward the caveat that this definition ofthe coupling is a gauge dependent one, the general relevance of such an occurrenceis discussed. We fit  (nf=0)MS = 237 ± 3+ 0−10MeV in perfect agreement with the resultobtained by the ALPHA group with a totally different method. The power correctionto α^MOM(p) is fitted to (0.63 ± 0.03+ 0.0− 0.13)GeV²/p².
