Williamson is a town on the south shore of Lake Ontario in the northwest part of Wayne County, New York, United States.

The area around Pultneyville — a hamlet on the town's Lake Ontario shore – was a frequent meeting ground for Iroquois people.

This hamlet briefly enjoyed prominence as one of the few ports in the area until the opening of the Erie Canal in the southern part of the county in 1823.

In 1814, during the War of 1812, British troops landed in Pultneyville, and an agreement was made with the villagers allowing the invaders to seize some stores without resistance, but a dispute broke out and weapons fire began on both sides.

In 1980, the northern terminus of New York State Route 21 (NY 21) was moved southward from the intersection with Lake Road in Pultneyville to its present location at the intersection with NY 104, in Williamson, about 0.7 miles (1.1 km) north of the town's business district.

A number of local points of interest are considered popular landmarks by residents and visitors alike.

With its red and white color theme, summer employment there is considered a rite of passage for the town's teenagers.

Another noted eatery is the Candy Kitchen, located on West Main Street in the business district.

Celebrating the town's (and region's) heritage of apple farming, this event is held in May at the height of the blooms.

Recognized nationally for its fruit-growing – especially apple tarts, peach pies, and cherry cokes – local agriculture also includes dairy farming.

Unlike the rest of the country, however, Prohibition was not completely repealed in Williamson in 1933; this didn't occur until more than six decades later, in 1996.

It wasn't until after the turn of the century, in 2004, that voters again loosened the regulations and allowed alcohol service in restaurants, as well as permitting winery licenses for farms and the opening of liquor stores.
