Sheffield (population 304) is a village and rural community in the single-tier municipality of Hamilton, Ontario. It is located just off Highway 8, on the municipality's boundary with the Region of Waterloo. It is ten kilometres from the city of Cambridge and thirty-five from Hamilton's downtown core. The village lay on the road between the two cities until 1959, when the Sheffield Bypass was completed. Ontario Highway 8 still follows the route of the bypass; the main street through Sheffield is now a 2.4 km section of municipal road known as Old Highway 8.

Located approximately three kilometres north-east of Sheffield is a major tourist attraction, the African Lion Safari.
Sheffield had been settled by the early 1800s, and the village was founded by Rev. John A. Cornell, an immigrant from Dutchess County, New York who settled at the site in 1809. He became a preacher in 1812, founding the first church in Beverly Township. Church services were initially held in Cornell's barn and house, and in neighbouring communities. In 1834, a church was built by Cornell's congregation in Sheffield. The current United Church in Sheffield sits on the same site.
Sheffield was originally known as "The Cornell Settlement", but was named "Sheffield" by John A. Cornell with the establishment of the first post office circa 1832.
By 1857, Sheffield's village population was 150, and the village included a general store/post office, shoemaker, blacksmith, physician/surgeon, wagon maker, and hotel ("Sheffield House"). There was also a public school and three churches: the United Brethren in Christ (John A. Cornell's original congregation), the Wesleyan Methodists, and the Church of England (at Romulus). By at least 1868 there was a tailor. Throughout its history, most of the population of the Sheffield community have been farmers.
