Top Gear Australia is an Australian motoring reality television series, based on the British BBC series Top Gear. The programme first premiered on SBS One on 29 September 2008. A second season was ordered following the high ratings for the premiere episode and positive comments from advertisers, and the second season began broadcasting from 11 May 2009. After acquiring the rights to broadcast the UK version in 2009, the Nine Network started airing their own version of Top Gear Australia in September 2010. Top Gear Australia returned for a fourth season in 2011. The show was cancelled on 28 April 2012 due to declining ratings. An eight part series returned in 2024 on Paramount+ with new hosts.

Top Gear Australia is also the name of a licensed version of the British Top Gear magazine. The Australian magazine is produced by ACP Magazines (Australian Consolidated Press). The magazine features articles from many writers including Steven Corby, Craig Jamieson, Bill Mckinnon, James Stanford, Ben Smithurst, Jason Barlow, Sam Phillip, Ollie Marriage, Dan Read and Paul Horrell.

In October 2023, it was announced that the series would be revived by BBC Studios Australia with hosts Blair "Moog" Joscelyne, Beau Ryan and Jonathan LaPaglia, as an eight part fifth series which premiered on 17 May 2024 on Paramount+.
