OzAsia Festival, or simply OzAsia, is an Asia-focused arts festival in South Australia, presented by the Adelaide Festival Centre for two weeks in late October to early November each year. It features theatre, dance, music, film and visual arts from across Asia as well as outdoor events and food stalls. In some years it has focused on specific regions or countries in Asia.

Adelaide Festival Centre, Australia's first capital city multi-purpose arts centre and the home of South Australia's performing arts, was built in the 1970s, designed by Hassell Architects. Located on Kaurna Yarta, the Festival Theatre opened in June 1973 with the rest of the centre following soon after. The complex includes Festival Theatre, Dunstan Playhouse, Space Theatre and several gallery and function spaces. Located approximately 50 metres (160 ft) north of the corner of North Terrace and King William Road, lying near the banks of the River Torrens and adjacent to Elder Park, it is distinguished by its two white geometric dome roofs, and lies on a 45-degree angle to the city's grid.
