A random walk on a graph G has anomalous diffusion if the mean square deviation after n steps is sublinear in n. Systems that have, or are expected to have, anomalous diffusion include some regular exact fractals, and random graphs at their critical point. I will discuss these, and in particular what we know about diffusion on critical percolation, the uniform spanning tree, and random planar triangulations.
