The community was first settled in 1813 by Peter Henderson. The village was incorporated in 1876 as "Sand Bank." In 1890, the population was 551. On November 10, 2010, residents of Altmar voted to dissolve their village's government under Governor Andrew Cuomo's Government Reorganization and Citizen Empowerment Act, becoming the first village to do so under the act; the margin was a mere six votes. The village board had until May 31, 2011 to draft a plan to dissolve the village's government. The village was dissolved on June 1, 2013 and remains an area within the Town of Albion.

Located within Altmar is the Salmon River Fish Hatchery, operated by the New York State Department of Environmental Conservation to support the state's stocking program for Lake Ontario and Lake Erie. The hatchery is a popular destination for visitors, many of whom come to watch egg collections from steelhead, coho salmon and Chinook salmon returning to the hatchery. Over three million young fish are raised at the hatchery each year.
