Fort Erie is a town situated in the Niagara Region of Ontario, Canada, occupying the southeastern corner of the region on the banks of the Niagara River. It lies directly across the Canada–United States border from Buffalo, New York. As a municipality within the Niagara Region, it serves as a key transit point and residential community for larger areas in southern Ontario, functioning as both a retirement destination and a tourist hub due to its strategic location and proximity to major urban centers.

The area was originally settled by demobilized soldiers from Butler's Rangers after the American Revolution and named Bertie Township in 1784. A fort was established in 1764, playing a prominent role during the War of 1812 when it was attacked, captured, and destroyed by American forces. The town underwent significant administrative changes, including the 1970 amalgamation of Bertie Township with the village of Crystal Beach to form the present Town of Fort Erie, consolidating various villages into a single municipal entity.

The town features several commercial core areas including Bridgeburg, Ridgeway, Stevensville, and Crystal Beach, developed largely following the 1970 amalgamation. Notable landmarks include Old Fort Erie, which was rebuilt as a tourist attraction in 1939, and the Point Abino Lighthouse, designated a National Historic Site after its decommissioning in 1995. The landscape includes low sand hills along Lake Erie and a limestone ridge that gives Ridgeway its name, while Garrison Road serves as the primary east-west commercial corridor.

Fort Erie attracts visitors with its beaches, notably Crystal Beach and Erie Beach, which were historically home to amusement parks drawing crowds from Buffalo until the mid-20th century. The Niagara Movement meeting was held at the Erie Beach Hotel in 1905, leading to the founding of the NAACP. Today, attractions include Fort Erie Race Track, Safari Niagara, and the Point Abino Lighthouse, which offers weekend tours in the summer, capitalizing on its heritage status and waterfront appeal.

In the 2021 Census, Fort Erie had a population of 32,901 living in 14,081 private dwellings, representing a 7.1% increase from 2016. The median household income in 2015 was $60,800, below the provincial average. Transportation access is provided by the Queen Elizabeth Way since 1937 and the Peace Bridge to Buffalo, built in 1927. Summers are enjoyable for beach activities, while winters can be fierce with snowstorms and winds coming off Lake Erie.
