By high-resolution scanning transmission electron microscopy (STEM) of epitaxial single crystal (001)-oriented TiN films, we identify different dislocation types and their core structures. These include, besides the expected primary full a/2{110}<1$\\bar{1}$0> dislocation, Shockley partial dislocations a/6{111}<11$\\bar{2}$> and sessile Lomer edge dislocations a/2{100}<011>.
