Caledon (/ˈkælədən/; 2021 population 76,581) is a town in the Regional Municipality of Peel in the Greater Toronto Area of Ontario, Canada. The name comes from a shortened form of Caledonia, the Roman name for what is now Scotland. Caledon is primarily rural with a number of hamlets and small villages, but also contains the larger community of Bolton (population 26,795) in its southeastern quadrant, adjacent to York Region. Some spillover urbanization also occurs in the south bordering the City of Brampton.

Caledon is the northernmost of three municipalities of Peel Region. The town is northwest of Brampton. According to Statistics Canada the land area is 688 km (266 sq mi) and, according to the city the area is 696.04 km (268.74 sq mi), which makes Caledon the largest municipality by area in the Greater Toronto Area.

By 1869, Belfountain was a village with a population of 100 in the Township of Caledon County Peel. It was established on the Credit River. There were stagecoaches to Erin and Georgetown. The average price of land was $20.

In 1973, Caledon acquired more territory when Chinguacousy dissolved, with most sections north of Mayfield Road (excluding Snelgrove) transferred to the township.

Caledon inherited the name from Caledon Township of Peel County, Ontario, in 1974, which was likely named by settlers like Edward Ellis, who came from the area around Caledon, County Tyrone, now in Northern Ireland, or by public voting.

In 1974, Peel County's 10 municipalities became the Region of Peel's 3 municipalities. The Town of Caledon was created from the villages of Bolton and Caledon East, the townships of Albion and Caledon, and the north half of Chinguacousy.

The primary administrative and commercial centre of Caledon is the community of Bolton, which the federal government estimated as having a population of 26,795 in 2021.

Highways in the municipality:

• Highway 10 (Hurontario Street)

Former highways (now Regional roads):

• Charleston Sideroad or Peel Road 24 (formerly Highway 24 west of Highway 10)

GO Transit operates two bus routes in Caledon:

• serving Bolton along Highway 50 and through east Mississauga and connecting with Malton GO Station on the Kitchener line.
• serving Orangeville and Brampton and connecting with Brampton GO Station on the Georgetown line via Highway 10 and Brampton's Main Street.

Due to its largely rural nature, Caledon does not have its own transit system; however, Brampton Transit provides a rush hour-only bus line, 41 Bolton in Bolton and travels south down Highway 50 in to Queen Street/Highway 7 (at the border of Brampton and Vaughan) to make connections with other Brampton Transit routes and York Region Transit (YRT). Brampton Transit also operates three other routes short distances into suburban areas bordering Brampton within the town: Route 81 Mayfield West serves Kennedy Road in Mayfield West, and Routes 18 Dixie and 30 Airport Road provide limited service into industrial areas.

Paratransit services for the elderly, disabled, and infirm are provided by Caledon Community Services Transportation and Transhelp. Both are run by the Region of Peel Accessible Transportation Services.

There were two earlier privately-operated transit services running solely within Bolton with no connections to other services: In 1999 a company named Caledon Transit Incorporated ran a trial bus service in the community. In 2006, the growing population of Bolton prompted local resident Darren Parberry to start a second bus service with two routes using leased school buses, called Métis Transit. One route ran briefly in 2006. Both services ceased operations due to low ridership. Between 2019 and 2024, there was a third service, operated by a private contractor, Voyago, which provided minibus service in Bolton and traveled south down Highway 50 to Queen Street/Highway 7 to connect with Brampton Transit and YRT until it was replaced by the current Brampton Transit Route 41 on May 1, 2024. Adult cash fares were $4.00 and there were no free transfers with these systems.
