Abstract: In this paper, we discuss reducing subspaces of multiplication operators on the Dirichlet space defined by a Blaschke product with two zeros , in the unit disk and show that when , has two proper ones; otherwise it has none. This is different from the cases of the Hardy space and the Bergman space.
