The Iron Horse Regional Trail is a railroad track for pedestrians, horse riders and bicycles in the East Bay Area of California.

This trail is located in the inland central Alameda and Contra Costa counties, mostly on the Southern Pacific Railroad right of way established in 1891 and abandoned in 1977. The two counties purchased the right of way at that time, with the intention of using it as a transport corridor; the Iron Horse Trail was first established in 1986. In 2003, BART also proposed to use the DMU line right-of – way from Walnut Creek to Tracy via Pleasanton.

The trail runs through the cities of Pleasanton, Dublin, San Ramon, Danville, Alamo, Walnut Creek, Pleasant Hill and Concord. When completed, the trail will run from Livermore in central Alameda County to Suisun Bay on the northern edge of Contra Costa County, a distance of more than 40 miles (64 km) from two counties and nine communities. The trail also connects directly to both Dublin / Pleasanton and Pleasant Hill BART stations.

The trail is maintained by the Regional Park District of East Bay. It is a wheelchair accessible paved trail along adjacent unpaved or soft trails in some areas.The Iron Horse Regional Trail has several bridges over busy thoroughfares to help improve traffic flow; two notable bridges cross Ygnacio Valley Road in Walnut Creek and Treat Boulevard in Contra Costa Centre. Additional bridges are part of the planning process. Despite initial scepticism and even opposition, the trail is now a major transport and recreation corridor. One million trips are made each year along the way.
