We prove several optimal‐order error estimates for a ?1 finite‐element method applied to an inhomogeneous Robin boundary value problem (BVP) for the Poisson equation defined in a smooth bounded domain in ℝn$$ {\mathbb{R}}^n $$ , n=2,3$$ n=2,3 $$ . The boundary condition is weakly imposed using Nitsche's method. The Robin BVP is interpreted as the classical penalty method with the penalty parameter ε$$ \varepsilon $$ . The optimal choice of the mesh size h$$ h $$ relative to ε$$ \varepsilon $$ is a non‐trivial issue. This paper carefully examines the dependence of ε$$ \varepsilon $$ on error estimates. Our error estimates require no unessential regularity assumptions on the solution. Numerical examples are also reported to confirm our results.
