We provide an entropy formulation for porous medium-type equations with a stochastic, non-linear, spatially inhomogeneous forcing. Well-posedness and L 1-contraction is obtained in the class of entropy solutions. Our scope allows for porous medium operators Δ (| u| m− 1 u) for all m∈(1,∞), and Hölder continuous diffusion nonlinearity with exponent 1/2.
