We study the impurity bound states in d-wave charge and spin density wave (CDW \& SDW) phases, which are candidate models for the pseudogap regime in the high-T_c cuprates. The Bogoliubov--de Gennes equations for a single impurity are solved. When the impurity is nonmagnetic, there is no distinction between CDW and SDW. The bound state wave function exhibits a fourfold symmetry pattern analogous to the d-wave superconducting phase. In addition, the wave function exhibits a checkerboard-like pattern, previously observed around the vortex bound states in the underdoped region of Bi2212. These predictions should be readily accessible to scanning tunneling microscope experiments.
