We discuss the isospin-breaking mass differences among baryons, with particular attention in the charm sector to the $\Sigma_c^{+}-\Sigma_c^0$, $\Sigma_c^{++}-\Sigma_c^0$, and $\Xi_c^+-\Xi_c^0$ splittings. Simple potential models cannot accommodate the trend of the available data on charm baryons. More precise measurements would offer the possibility of testing how well potential models describe the non-perturbative limit of QCD.
