A Baer ring is a ring $R$ in which every left annihilator is generated by an idempotent $e$. The analogous definition in terms of right annihilators is equivalent . A Baer ring is necessarily a left and a right Rickart ring.

Examples of Baer rings include integral domains, and matrix rings over a field.
