The effect of Z3 symmetry on the general Two Higgs Doublet Model is explored. Of particular interest is the question of what can a Z3 symmetry do beyond the usual case with Z2. There are two independent scenarios that give some interesting results: first, by giving non-trivial charges to the Standard Model fermions, it is possible to use the Z3 symmetry of the scalar potential to generate potentially useful Yukawa textures. This is not possible with Z2. A series of possibilities is presented where their viability is addressed and a specific example in the quark sector is given for concreteness. The second venue of interest is in the area of inert doublets. It is shown that by considering the Standard Model plus two additional inert doublet scalars, i.e. a Dark Two Higgs Doublet Model, together with Z3, a scenario can be obtained that differs from the Z2 case. Some general comments are presented on the potentially interesting phenomenology of such model.
