In this paper we study the effects of noncommutative phase space deformationson the Schwarzschild black hole. This idea has been previously studied in{Friedmann-Robertson-Walker (FRW)} cosmology, where this "noncommutativity"provides a simple mechanism that can explain the origin of the cosmologicalconstant. In this paper we obtain the same relationship between thecosmological constant and the deformation parameter that appears in deformedphase space cosmology, but in the context of the deformed phase space blackholes. This was achieved by comparing the entropy of the deformed Schwarzschildblack hole with the entropy of the Schwarzschild-de Sitter black hole.
