Emu (Dromaius) je rod běžce z australské oblasti. Jediným žijícím druhem je emu hnědý (Dromaius novaehollandiae), dále členěný na několik poddruhů. K němu se přidružují i druhy Dromaius ocypus a Dromaius arleyekweke, jež jsou známy pouze z fosilních pozůstatků. Rod emu popsal Louis Pierre Vieillot roku 1816, přičemž odborně jménem je Dromaius nebo Dromiceius.

Geographic distribution of emu taxa and historic shoreline reconstructions around Tasmania.
Modern Emu are currently found throughout mainland Australia. Extinct emu taxa were restricted to their respective islands: the Kangaroo Island Emu (purple), the King Island Emu (red) and the Tasmanian Emu. Twenty-five thousand years ago Tasmania, Flinders and King Island were connected to mainland Australia. Approximately 17,500 years ago King Island lost its direct connection with mainland Australia. By 14,000 years ago Tasmania, Flinders and King Island started to disconnect from the mainland, but were still connected to each other. By 11,000 years ago King Island was isolated from Tasmania, while the Tasmania was still connected to Flinders Island. Presently Tasmania, Flinders, King and Kangaroo Island are all isolated and disconnected from mainland Australia (modified from Lambert DM, Ritchie PA, Millar CD, Holland B, Drummond AJ, et al.
