Parramatta Stadium (known as Pirtek Stadium for sponsorship purposes) was an Australian sports stadium situated in Parramatta, Sydney, New South Wales, 23 kilometres west of the Sydney central business district. The stadium is used as the home ground of Western Sydney sports teams: Parramatta Eels (National Rugby League), Western Sydney Wanderers (A-League) and Greater Sydney Rams (National Rugby Championship). The site had previously been occupied by Cumberland Oval.

The stadium has also hosted numerous other sporting and cultural events since its opening in 1986. Michael Jackson performed there during his Bad World Tour on 20–21 November 1987, and Paul McCartney concluded the Australian leg of The New World Tour with two shows there on 22–23 March 1993.

In September 2015, the NSW Government announced that the stadium would be demolished and rebuilt with upwards of 30,000 capacity. The build cost is expected to be in the $300 million range, and will result in the stadium being knocked down in late 2016. The new stadium is expected to take 3 years to be completed.
