Adelaide Writers' Week, known locally as Writers' Week or WW, is a large and mostly free literary festival held annually in Adelaide, the capital of South Australia. It forms part of the Adelaide Festival of Arts, where attendees meet, listen, and discuss literature with Australian and international writers in "Meet the Author" sessions, readings and lectures. It is held outdoors in the Pioneer Women's Memorial Garden.
Each Adelaide Writers' Week includes six days of free panel-sessions presented live in the gardens, later made available online via podcast. Selected sessions are shown live via videolink in some libraries. The programme also features a series of ticketed special events, both at Festival time and throughout the year, and there is a free "Kids' Weekend", at which children's authors present their work for a range of ages and other activities take place.
