The Sydney Olympic Park bus routes are a network of special event bus routes designed to transport passengers to the Sydney Olympic Park suburb of Sydney, Australia during major events.
During the planning of the 2000 Summer Olympics, the Government of New South Wales committed to a public transport-only strategy for the games. To discourage private vehicle use, the city provided minimal parking at competition venues and focused on the development of a new transit hub and the Olympic Park railway line. To address areas of the city that remained without access to public transportation after these additions, a dedicated network of bus routes was developed and commenced operation in 1998 to coincide with the relocation of the Sydney Royal Easter Show from Moore Park to the new Olympic venue.
The bus routes are activated for major events as designated by the state government, including:
