Abstract: In this paper we characterize the commutants of two classes of analytic Toeplitz operators. We show that if $ F$ in $ {H^\infty }$ is univalent and nonvanishing, the $ \{ {T_{{F^2}}}\} ' = \{ {T_z}\} '$. When $ \varphi $ is the product of two Blaschke factors, we characterize $ \{ {T_\varphi }\} '$ in terms of algebraic combinations of Toeplitz and composition operators.
