contents It is well known that non-negative solutions to the Dirichlet problem $Δu =f$ in a bounded domain $Ω$, where $f\in L^q(Ω)$, $q>\frac{n}2$, satisfy $\|u\|_{L^\infty(Ω)} \leq C\|f\|_{L^q(Ω)}$. We generalize this result by replacing the Laplacian with a degenerate elliptic operator, and we show that we can take the data $f$ in an Orlicz space $L^A(Ω)$ that, in the classical case, lies strictly between $L^{\frac{n}{2}}(Ω)$ and $L^q(Ω)$, $q>\frac{n}2$.
