The Franklin Regional Transit Authority (FRTA) is a regional transit authority which provides public transportation principally to Franklin County and the North Quabbin region, both in Massachusetts. The FRTA is based in the county seat of Greenfield, Massachusetts.

Prior to the FRTA, Greenfield and its surrounding areas were served by the intermunicipal Greenfield and Montague Transportation Area (GMTA), an authority created with the purchase of assets of the defunct Connecticut Valley Street Railway in 1924.^[4] The FRTA was established in 1978 with then implementation of Massachusetts General Laws Chapter 161B, which gave rise to several regional transit authorities throughout Massachusetts. FRTA is the largest public transit authority in Massachusetts by territory.

In 1999, the FRTA and the Fitchburg-based Montachusett Regional Transit Authority (MART) cooperated to form a route to Athol and Orange, Massachusetts, linking Greenfield to the MART terminal in Gardner.

Although not in the FRTA service area, public bus service operated by the Pioneer Valley Transit Authority between Greenfield and Northampton began in 2000.

In 2006, the FRTA assumed the responsibility of providing transportation services for the towns of Greenfield and Montague, when the former Greenfield Montague Transportation Area (GMTA) transit authority became unfunded by the state Department of Transportation.^[5]

In 2013, Athol voted to withdraw from the FRTA service district, and instead voted to join MART, necessitating that the former Greenfield/Athol route be truncated in Orange.

FRTA public transportation service is available Monday through Friday. Fares on fixed route buses are free through June 30, 2024. FRTA is classified as a 'rural' transit authority.^{[citation needed]} As of May 2023^[update], there are seven active routes:^[1]
