Richmond is a town in Ontario County, New York, United States.  The population was 3,380 at the 2020 census. The town is named after Abigail Richmond Pitts, an early settler. The town of Richmond is on the western border of the county, south of Rochester.
 Richmond was part of the Phelps and Gorham Purchase. The area was first settled around 1790. The town was established in 1796 as "Pittstown", after Captain Peter Pitts, but was later renamed "Honeoye." In 1815, the name was changed to "Richmond", after Peter Pitts' wife, Abigail Richmond Pitts, a direct descendant of the Pilgrims.  More territory was added to Richmond from the Town of Canadice in 1836. Parts of the Towns of Bristol and South Bristol were added to Richmond in 1848, but were returned to the source towns in 1852.
 In 1600 the Honeoye Lake Watershed was—apart from clearings made by Native Americans and natural causes such as fire, steep slope landslides, wind or ice—completely forested. The watershed’s primeval forest contained massive trees, some covering as much as a half-acre of ground.
 Early settlers found these forests useful. Probably the first product to be transported to market was barrels of potash, made from ashes of the burned trees. As sawmills were erected, lumber from the trees cut from  1830 to 1890 were used in the construction of urban centers such as Rochester, Buffalo, and Syracuse.
 Efforts to bring logs down from the inaccessible area between East Lake Road and Gulick led to the  construction of a rail line in the bottom of Briggs Gully. In 1885, maximum deforestation and  agricultural land use arrived in New York State, often on lands that would not support these practices. Since 1885, there has been a slow decline of farming in the watershed, accelerated by the Great  Depression from 1929 to 1943 and a gradual re-establishment of the area’s forests.
 Changes in the character of the Town of Richmond and Honeoye Lake Watershed over the past half century have been significant. The growth in the use of private automobiles and the construction of good roads in the 1920s and 1930s added to the desirability of Honeoye lakefront cottages. By the mid-twentieth century, undeveloped lake frontage had mostly disappeared and summer cottages filled the shoreline.
 The years after World War II also signaled the end of agriculture as a principal use of the watershed land and the rapid residential development in the hills of Richmond and Canadice overlooking the lake. The reduction of agriculture resulted in the natural re-forestation of inactive agricultural lands, which was beneficial in reducing erosion. However, increased residential development resulted in the loss of native vegetation and an increase in impermeable surfaces.  These historical changes in the watershed have impacted the watershed character and the water quality— both for better and worse.
 In 1962, the Honeoye Chamber of Commerce organized a first Winter Carnival. The event became so popular that in 1971 over 50,000 visitors arrived—tying up traffic for miles. After considerable success, the Winter Carnival was discontinued due to lack of tourist infrastructure. Recent studies by the Ontario County Tourism Bureau have documented the major economic benefits of special festivals and occasions to Ontario County communities.  The summer population has been estimated at 4,500.
 According to the United States Census Bureau, the town has a total area of 44.3 square miles (115 km2), of which 42.4 square miles (110 km2)  is land and 1.9 square miles (4.9 km2)  (4.29%) is water.
 The western town line is the border of Livingston County. Most of Honeoye Lake, one of the minor Finger Lakes, is inside the town. Honeoye Creek, the lake's outlet, flows northward through the town.
 US 20A crosses the town.
