Riot Sydney (formerly BigWorld Technology and Wargaming Sydney) is an Australian software company, formed in 2002 by John De Margheriti. It was the developer of BigWorld, a middleware development tool suite for creating massively multiplayer online games (MMO) and virtual worlds. It was the first company that developed a middleware platform for the MMO market. In 2007, BigWorld was recognised by the UK's Develop magazine as an industry leader.

On 7 August 2012, Wargaming — which had used BigWorld as part of the infrastructure for games such as World of Tanks — acquired BigWorld Technology for $45 million. Wargaming stated that it would continue to license and support BigWorld, and foresaw the possibility that it could offer its technologies with BigWorld for third-party licensors. The studio was operated as Wargaming Sydney. On 17 October 2022, Wargaming sold the studio to Riot Games for an undisclosed amount, renaming it to Riot Sydney; the sale excluded the BigWorld technology itself and the studio's publishing arm, which will be retained by Wargaming.
