  We review the present status of the Anderson transition in the spectrum of
the Dirac operator of QCD-like theories on the lattice. Localized modes at the
low-end of the spectrum have been found in SU(2) Yang-Mills theory with overlap
and staggered valence fermions as well as in Nf=2+1 QCD with staggered quarks.
We draw an analogy between the transition from localized to delocalized modes
in the Dirac spectrum and the Anderson transition in electronic systems. The
QCD transition turns out to be in the same universality class as the transition
in the corresponding Anderson model. We also speculate on the possible physical
relevance of this transition to QCD at high temperature and the possible finite
temperature phase transition in QCD-like models with different fermion
contents.
