List of rail trails in Massachusetts

This list of rail trails in Massachusetts details former railroad right-of-ways in Massachusetts that have been converted to trails for public use and proposed rail trails where trails exist but have not been fully established.

Massachusetts has at least 69 rail-trails, covering 347 miles. A massive new project proposed by the Metropolitan Area Planning Council, called the Landline, seeks to connect these trails, creating a 1,400-mile network of greenways and foot trails within the Boston region. When finished (currently 45 percent of the greenway network and 60 percent of the foot trail network is complete), the network would bring trail access within a half mile of three-quarters of the region's residents, and 92 percent of residents would be within one mile of the nearest trail or path."
