The '''Australian Open''' (stylized '''ΛO''') is a [[tennis]] tournament organised by [[Tennis Australia]] annually at [[Melbourne Park]] in [[Melbourne]], [[Victoria (state)|Victoria]], [[Australia]]. It is chronologically the first of the four [[Grand Slam (tennis)|Grand Slam]] tennis events every year, held before the [[French Open]], [[Wimbledon Championships|Wimbledon]] and the [[US Open (tennis)|US Open]].

The Australian Open typically starts around the middle of January and continues for two weeks, concluding with the men's final traditionally held on the last Sunday of the month. It features men's and women's singles, men's, women's and mixed doubles, juniors’ championships, wheelchair, legends, and exhibition events.

Until 1987, it was played on [[grass court]]s, but since then three types of [[hardcourt]] surfaces have been used: green-coloured [[Rebound Ace]] up to 2007 and blue [[Plexicushion]] from 2008 to 2019. Since 2020, it has been played on blue [[GreenSet]].<ref>{{cite news | url=http://www.theage.com.au/news/tennis/australian-open-court-surface-is-speeding-up/2007/11/19/1195321694990.html | location=Melbourne | work=The Age | first=Stathi | last=Paxinos | title=Australian Open court surface is speeding up | date=20 November 2007 | access-date=23 December 2013 | archive-date=18 May 2014 | archive-url=https://web.archive.org/web/20140518105740/http://www.theage.com.au/news/tennis/australian-open-court-surface-is-speeding-up/2007/11/19/1195321694990.html | url-status=live }}</ref>
