The Amherst and Sunderland Street Railway was an interurban streetcar system that operated in Amherst, Sunderland, Pelham, Granby, and South Hadley, Massachusetts.
From 1897 until 1932, trolleys operated between Sunderland, the Massachusetts Agricultural College (now UMass Amherst), and connected with the Holyoke Street Railway's system at "The Notch" after 1902.
This rail line, providing freight and passenger service, was built by the short-lived Hampshire Street Railway specifically to connect the other two systems; the Hampshire Street Railway would lease the line to the Holyoke railway in 1905, which ultimately consolidated with it, along with Amherst & Sunderland, in 1907.
After the merger the name was kept as a legacy and lines to the north of the Holyoke Range were referred to as the Amherst and Sunderland Division of the Holyoke Street Railway.
While the HSR would continue operations in Amherst as a bus carrier, after trolley service ceased in 1932 the A&S name was dropped altogether.

The company was initially chartered on February 27, 1896, but was beset by legal troubles in its initial formation.
Among these setbacks was the sale of shares under the name the "Amherst Street Railway Company", which legally did not exist, prompting the board to have to take up entirely new shares from the same parties that they had first sold them to.
This issue had apparently arisen from an early board meeting during which a stockholder from Sunderland moved to append the town name to the railway company's, however none of the members had new paperwork printed to reflect this.
This problem was further complicated when then-president of the board, Levi Stockbridge, revealed the state railroad commissioners refused to recognize the company, as its charter had been accepted in the minutes of a meeting called by a single board member, rather than the entirety of the charter members.
Despite predictions by some that this was the end of the enterprise, Stockbridge urged that if the group did not organize to build the street railway, there were several other syndicates which would; by the end of their next meeting the group was able to recollect all necessary shares.

Following an extended period of discussion over the specific location of the tracks, work commenced in the laying of line in April of 1897, and by June of that year the first trolleys were operational.
While Stockbridge remains notable among founding figures of the street railway, his role as president of the company was limited to its first year, a greater credit was due to Walter D. Cowles, a member of the board and subsequent president of the company, whose family stored the streetcars in car barn facilities on the grounds of their lumber business in the railways earliest years.
In 1897 the railway began to see competition from the Northampton and Amherst Railway, later known as the Connecticut Valley Street Railway,, as it connected Northampton to Amherst, through Hadley.
Despite outcry from the Amherst & Sunderland Street Railway and its interests, by the end of 1897 the competitor had been given access and some consideration was given to franchise.
In response to this, the railway would attempt to expand its own holdings in Hadley, building a new line through Mill Valley to the Hadley border in the following year.

The railway's ties with the Holyoke Street Railway began in 1902 when the stockholders and directors voted to increase the capital stock of the company to construct a line across the Notch in the Holyoke Range and connect with the Hampshire Street Railway system at the Granby town line.
The Hampshire Street Railway, organized that same year, served as a collaboration of the interests of the Amherst and Holyoke railways, with Walter Cowls and William Loomis elected as sitting directors in the following year at an annual meeting at the Holyoke company's offices.
In the following year the railway began advertising jointly with the Holyoke Street Railway as the best way to reach "The Famous Amherst 'Notch'", and by 1905 the entirety of the system was leased to
