The Sydney Sports Ground No. 1 was a Stadium and dirt track racing venue in Sydney, New South Wales. The ground was located where the car park of the Sydney Football Stadium (SFS) currently sits. The ground had two main grandstands and was surrounded by a grass covered hill, giving it a capacity of more than 35,000. It was demolished along with the smaller No.2 Ground in 1986 to allow the building of the SFS, which opened in 1988. During its lifespan the sports ground hosted rugby league, rugby union, soccer, motorcycle speedway, and speedway car racing.
