Fyansford is a township on the western edge of Geelong, Victoria, Australia, named after Captain Foster Fyans who came to Geelong as a Police magistrate in October, 1837. It is located at the junction of the Barwon and Moorabool rivers. At the 2016 census, Fyansford had a population of 196.

The Hamilton Highway runs through the town. The first river crossing at Fyansford was a ford, with the first wooden bridge built downriver by the Corio and Bannockburn Shire councils in 1854, and was tolled until 1877. It was in poor condition by 1898, with load restrictions being put into place. A new bridge was built nearby in 1900 by John Monash and J. T. N. Anderson, the three-arch bridge being the largest Monier reinforced concrete bridge in the world at the time. In 1970 a new bridge was built on the site of the old wooden bridge to cater for heavier traffic on the Hamilton Highway, the 1900 bridge retained for pedestrians.
