The 1999–2000 Australian region cyclone season was a slightly above average tropical cyclone season. It ran from 1 November 1999 to 30 April 2000. The regional tropical cyclone operational plan also defines a "tropical cyclone year" separately from a "tropical cyclone season", with the "tropical cyclone year" for this season lasting from 1 July 1999 to 30 June 2000.

Two of the most notable cyclones of the season were Steve and Rosita. Cyclone Steve transversed the entire Australian continent, and although a fairly weak cyclone, caused widespread flooding in Queensland, Northern Territory and Western Australia, while Cyclone Rosita made an almost direct hit on Broome as a severe Category 4 cyclone, devastating several remote stations and the town itself. Rosita surprised many residents of its arrival, as it made landfall very late in the season.
