Do overcooked hard-boiled eggs smell bad?

Yes, overcooked hard-boiled eggs often smell bad, developing a strong, pungent sulfur odor and a greenish-gray ring around the yolk due to a chemical reaction between iron in the yolk and sulfur in the white, making them less appetizing but generally still safe to eat. This intensified smell comes from hydrogen sulfide gas forming from sulfur compounds when cooked too long.
