Spectral methods are considered for use in numerical relativity. A particular implementation of a pseudospectral collocation method for Cauchy evolution is described. The treatment of boundary conditions in this method automatically handles black hole excision, given an appropriate system of evolution equations and an appropriate gauge choice. Some numerical results are shown.
