Brighton is a municipality in Northumberland County, Ontario, Canada,

The original Simpson house, at 61 Simpson Street, was built in 1850. Brighton developed primarily into an agricultural community, specializing in the farming of apples and production of new apple types. However, in recent years, many of the original orchards in the area have been partially removed, to make way for the steadily growing population, and more profitable agricultural produce, such as wheat, corn and soybeans.

On January 1, 2001, the current Municipality of Brighton was formed through an amalgamation of the former Town of Brighton and Brighton Township.
