We review recent progress in the study of the large Nc limit of gauge theories from lattice simulations. The focus is not only the planar limit but also the size of \mathcal O(Nc-1) corrections for values of Nc\gtrsim 3. Some concrete examples of the topics we include are tests of large-Nc factorization, the topological susceptibility, the glueball, meson and baryon spectra, the chiral dependence of masses and decay constants, and weak matrix elements related to the ΔI=1/2 rule in kaon decays.
