With a population of 4,633, Mount Morris is the fifth largest town in Livingston County.

Mount Morris was founded by General William A. Mills who was also one of the founders of Livingston County. It is one of four communities so named in the United States. The others are in Pennsylvania, Michigan, and Illinois.

It was named for Robert Morris, on of the principal land purchasers in the Holland Purchase. After completion of the $30 million Mount Morris flood control dam on the Genesee River in 1952, the town was christened with the sobriquet, "Best Town by a Dam Site."

Mount Morris is the birthplace of Francis Bellamy, author of the Pledge of Allegiance, Major John Wesley Powell, explorer of the Colorado River, and Ross Barnes, first batting champion of the National Baseball League.

On the site of the former State TB Hospital, the County developed the Livingston County Campus. The 100 bed health resources facility provides a home and medical supervision for senior citizens. Numerous other county departments are located on the campus, along with a beautiful wooded County Park where picnic and recreational facilities are available.

The headquarters of the Board of Cooperative Educational Services, its Charles G. May Occupational Center, and the Cooperative Extensive headquarters are all located within the village.

The Genesee Expressway (I-390) provides Mt. Morris with easy access to the Rochester Area Business Districts and the Rochester International Airport. Interstate 390 connects the town with Federal Highways 36, 408 and the New York State Thruway for long haul travel as well as shorter metropolitan trips.
