The entropy of the BTZ black hole is computed in the Ponzano–Regge formulation of three-dimensional lattice gravity. It is seen that the correct semiclassical behavior of entropy is reproduced by states which correspond to all possible triangulations of the Euclidean black hole. The maximum contribution to the entropy comes from states at the horizon.
