The Main Yarra Trail, also known as the Yarra Trail is a shared-use path for cyclists and pedestrians, which follows the Yarra River through the northeastern suburbs of Melbourne, Victoria, Australia.

The trail follows the river from near its mouth, through the city and suburbs to Westerfolds Park and Eltham. The Capital City Trail uses the same path up to Dights Falls, where it continues up the Merri Creek Trail as part of its loop around the city.

The first section to be built was between the Princes Bridge and Punt Road to the south of the Melbourne central business district, which opened in November 1975. The second section from Punt Road to the MacRobertson Bridge in Toorak and third section to Hawthorn Bridge were built in subsequent years.

Further extensions and improvements to the Trail were planned and funded as part of the Melbourne Bikeway Plan published in 1976, developed by the state Ministry of Transport and the University of Melbourne following extensive lobbying by Keith Dunstan of Bicycle Victoria.

The initial stages of the path were very successful with high usage. This sparked several campaigns to continue the route along the River northeast into Hawthorn, Kew, and Fairfield. The neighboring municipalities of Hawthorn and Kew began purchasing residential frontages to prepare for future construction of the Trail.

In November 1991, the bridge over the Yarra River at Finns Reserve was constructed. This brought the total length of the Trail to 20 kilometers at the time.

The path starts just to the north of West Gate Bridge near the mouth of the Yarra River as it enters Port Phillip Bay by the punt landing, allowing cyclists and pedestrians to cross to Spotswood and the Hobsons Bay Coastal Trail.

From the punt landing, the trail winds through Melbourne Docklands, initially as a dedicated path on Lorimer Street, and then, east of Todd Road it continues as an on-road cycling lane along Lorimer Street.^{[citation needed]}
