The Old Colony Railroad (OC) was a major railroad system, mainly covering southeastern Massachusetts and parts of Rhode Island. It operated from 1845 to 1893. Old Colony trains ran from Boston to points such as Plymouth, Fall River, New Bedford, Newport, Providence, Fitchburg, Lowell and Cape Cod. For many years the Old Colony Railroad Company also operated steamboat and ferry lines, including those of the Fall River Line with express train service from Boston to its wharf in Fall River where passengers boarded luxury liners to New York City. The company also briefly operated a railroad line on Martha's Vineyard, as well as the freight-only Union Freight Railroad in Boston. The OC was named after the "Old Colony", the nickname for the Plymouth Colony.

From 1845 to 1893, the OC network grew extensively largely through a series of mergers and acquisitions with other established railroads, until it was itself acquired by the New York, New Haven and Hartford Railroad under lease agreement on March 1, 1893 for its entire 617-mile (993 km) network. After this date, all trains, lines, and stations became known as the "Old Colony Division" of the huge "New Haven" system. During this period, the New York, New Haven and Hartford Railroad enjoyed a virtual monopoly on all passenger and freight rail service in southern New England.
