We prove that any compact hyperbolic Coxeter polytope except some well-known low-dimensional examples has a pair of disjoint facets. This is one of very few known general results concerning combinatorics of compact hyperbolic Coxeter polytopes. We also obtain a similar result for simple non-compact polytopes.
