Three Hills was incorporated as a village in 1912, the year it was moved to its current location on the Canadian Northern Railway. With ranchers and farmers constituting its first residents, it soon became a centre for the surrounding wheat-growing area.
In 1922, the Prairie Bible Institute (now called Prairie College) was established in Three Hills with L. E. Maxwell as its founding principal. This occurrence helped to increase the population of the town proper and its adjacent settlements. By the mid 1980s, the 130-acre (0.53 km2) College campus and the nearby hamlets of Grantville and Ruarkville were annexed to the town.
Although a relatively small community, Three Hills had the distinction of hosting the Alberta Seniors Games in the summer of 1998. The town was chosen to host this event because of its ability to utilize large and well equipped facilities at the college. This included the opening and closing ceremonies which took place in the 4,300 seat Maxwell Memorial Tabernacle, located on Prairie College's campus.
The Maxwell Tabernacle was Canada's largest religious auditorium before it was demolished in 2005. It operated from 1954 to 2005 as a local church, concert hall, and graduation auditorium of Prairie Christian Academy and Three Hills School high school classes.
Because of development regarding the nearby methane fields, the food and lodging industries in Three Hills have grown considerably over the past few years.

With a land area of 6.75 km2 (2.61 sq mi), it had a population density of 475.9/km2 (1,232.5/sq mi) in 2016.
In the 2011 Census, the Town of Three Hills had a population of 3,198 living in 1,178 of its 1,257 total dwellings, a 3.5% change from its 2006 population of 3,089. With a land area of 5.63 km2 (2.17 sq mi), it had a population density of 568.0/km2 (1,471.2/sq mi) in 2011.
Three Hills offers much to its community, including Three Hills Municipal Library, Aquatic Centre, Centennial Place hockey arena, curling rink, campground, Three Hills Golf Club, and the Kneehill Historical Museum. 
Since 1981, Three Hills has hosted an annual weekend in early June for auto enthusiasts called Cruise Night. The event typically attracts more than 8,000 visitors, along with their classic cars, trucks, motorcycles, and hot rods. This weekend is the largest of its kind in all of Western Canada.
