Classical gravitation is treated from the point of view of non-equilibrium thermodynamics. Gravitational potential is a thermodynamic state variable in a weakly nonlocal treatment. Entropy production is calculated and the simplest solution of the inequality with corresponding fluxes and forces is given. In case of ideal gravitation without dissipation one obtains the Poisson equation.
