The Australian Sex Party was an Australian political party founded in 2009 in response to concerns over the purported increasing influence of religion in Australian politics. The party was born out of an adult-industry lobby group, the Eros Association. Its leader, Fiona Patten, was formerly the association's CEO.

Patten described the party as a "civil libertarian alternative". Patten is a veteran campaigner on issues such as censorship, equality, and discrimination. Patten was elected to the Victorian Legislative Council at the 2014 state election.

The party was briefly federally deregistered by the Australian Electoral Commission (AEC) on 5 May 2015, after an audit found that it could not demonstrate that it met the statutory requirement of 500 members but was re-registered in July.

The Sex Party was registered at state level in Victoria, where it had parliamentary representation, as well as in the Australian Capital Territory and Northern Territory. In 2017, the party merged with the Australian Cyclists Party to form Reason Australia.
