Sorel-Tracy (/sɔːˈrɛl træˈsiː/; French: [sɔʁɛl tʁaˈsi]) is a city in southwestern Quebec, Canada and the geographical end point of the Champlain Valley.

Its mayor is Patrick Péloquin and it is the seat of the Pierre-De Saurel Regional County Municipality and the judicial district of Richelieu.

Early exploration in this area by the French was a catalyst for armed conflict with various indigenous peoples.

Its formation began in 1642 when Charles Huault de Montmagny, first Governor and Lieutenant-Governor of New France, built Fort Richelieu here as a defense for settlers and river travellers against the Iroquois, primarily the Mohawk, the powerful easternmost nation in the Confederacy based south of the Great Lakes.

It is probable that before the American Revolution, there were no English-speaking, Protestant people in Sorel, as it had been settled by French-speaking colonists and their descendants, who were primarily Catholic.

Governor Frederick Haldimand wrote a letter to Lord George Germain in October 1778, from his camp in Sorel where fortifications were in progress, proposing his use of the Seigneurie, It is my intention therefore, if time and circumstances favour me, to make Sorel a place of strength with Permanent Works, as the importance of it deserves.

The Seigneurie of this Place is vested in merchants residing in England and the Inhabitants of it, people remarkable for their courage and resolution, have distinguished themselves very much by their attachment to the Government even at a time the Rebels were Masters of that Country, in which account I think it would serve the King's interest to bestow some Public mark of favour upon them such as remitting them the Quitrents which they pay for their land, to the Seigneur, and the Seigneurie being to be sold, and the purchase would not exceed 13,000, having been offered for that sum, I submit to Your Lordship whether it would not be best to give orders to treat immediately with the Proprietors, Messrs. Greenwood and Higgins in London, both for enabling me to effect the purchase...The Crown purchased the land in 1781, at the end of the war, and Sorel became a clearing house for the steady stream of Loyalist refugees from the south.

With the continued influx of Loyalists during 1783 into the Seigniory (as the English spell it), the settlement sought a permanent Protestant minister.

The Reverend John Doty was assigned to the post, embarking during the month of April 1784 at Gravesend, England, and arriving at Quebec in June.

At the beginning of the 19th century, Sorel was a center of fur traders, who had been established in Quebec and among the indigenous peoples from the earliest years of the colony.

Due to his presence, the small town became a centre for the turbulent politics of that time, in the period leading up to the Lower Canada Rebellion.

Locally, the colonial governor and parish priest Jean-Baptiste Kelly competed for power and influence among the different ethnic groups.

The town changed its name back to Sorel from William-Henry in 1845, reflecting its demographics and predominately French Catholic population.

In the long term, the town continued to be settled primarily by French Canadians, rather than developing any sizable Anglo-Canadian population.

It was adapted as a 1973 film of the same name, directed by Claude Jutra and starring Geneviève Bujold and Richard Jordan.

MIL was also the site of construction of HMCS Bras d'Or, an experimental hydrofoil commissioned by the Royal Canadian Navy.

The city is home to QIT-Fer et Titane, a Titanium smelter and refinery now owned by the Rio Tinto corporation.

The team was known variously as Dinosaures, Mission, Royaux, GCI and HC Caverna before taking the name Sorel-Tracy Éperviers in 2012.
