heal.abstract	We study the Penrose limit of various AdS(p) x S-q orbifolds. The limiting spaces are waves with parallel rays and singular wave fronts. In particular, we consider the orbifolds AdS(3) x S-3/Gamma, AdS(5) x S-5/Gamma and AdS(4,7) x S-7,S-4/Gamma where Gamma acts on the sphere and/or the AdS factor. In the pp-wave limit the wave fronts are the orbifolds C-2/Gamma,C-4/Gamma and R x C-4/Gamma, respectively. When desingularization is possible, we get asymptotically locally pp-wave backgrounds (ALpp). The Penrose limit of the AdS(5) x RP5 orientifold as well as the pp-wave limit of D3-branes near singularities in F-theory are also presented. Finally, we give the embedding of D-dimensional pp-waves in at M-2,M-D space.	en
