The WACA (pronounced wakka) is a sports stadium in Perth, Western Australia. WACA are the initials of its owners and operators, the Western Australian Cricket Association.

The WACA ground has been the 'home' of cricket in Western Australia since the early 1890s. The first Test match was played at the ground in 1970.[1] The WACA has also been the home ground of the state of Western Australia's domestic cricket team, currently known as the Western Warriors. The women's cricket team known as the Western Fury plays in the Women's National Cricket League.

The pitch at the WACA was regarded as one of the quickest and bounciest in the world. These characteristics, in combination with the afternoon sea-breezes which regularly pass the ground (the Fremantle Doctor), have historically made the ground an attractive place for pace and swing bowlers.
