  Generalizations of QCD in which the number of colors N is taken to infinity
are characterized by profound mathematical properties, with far-reaching
implications for fundamental problems and for phenomenological issues alike. In
this contribution, after a brief introduction to the theoretical motivation for
studying the large-N limit, the role of lattice computations in large-N gauge
theories is discussed, and a selection of interesting results obtained in
recent years is highlighted. Finally, some promising research directions for
future studies are pointed out.
