The main aim of this paper is to integrate the relationships among rough set theory and topology. We introduce the interior and closure operators with respect to an ideal defined on an approximation space, generating an ideal approximation space. Some topological notions such as the subspace, continuous functions, lower separation axioms, and connectedness in ideal approximation spaces are defined and studied. Some examples are given to confirm the implications.
