We show that topological insulator crystals are an excellent plasmonic platform in the UV to near-IR part of the spectrum, thanks to the interplay of interband transitions and Drude-like response of metallic surface states. This opens up exciting opportunities for the integration of plasmonic, electronic and spintronic devices
