Polaris Inc. is an American automotive manufacturer headquartered in Medina, Minnesota, United States. Polaris was founded in Roseau, Minnesota, where it still has engineering and manufacturing facilities. The company manufactured motorcycles through its Victory Motorcycles subsidiary until January 2017, and currently produces motorcycles through the Indian Motorcycle subsidiary, which it purchased in April 2011. Polaris produced personal watercraft from 1994 to 2004. The company was originally named Polaris Industries Inc. and was renamed in 2019 to Polaris Inc.

Robin (a subsidiary of Subaru Corporation) previously developed and supplied all-terrain vehicle (ATV) and snowmobile engines for Polaris Inc. Starting in 1995 with the Polaris Magnum 425 4-stroke ATV and in 1997, with the introduction of the "twin 700" snowmobile engine Polaris started the development and production in house of the "Liberty" line of engines, now found in many models across their current production lines. Since that time Polaris has continued to develop their in-house engine production capacity, now designing and manufacturing all of their own power plants, while maintaining the partnership with Subaru.

In 2010, Polaris relocated a portion of its utility and sport vehicle assembly to Mexico. Components are manufactured in Osceola, Wisconsin and the vehicle assembly is done in Roseau, Minnesota. The vast majority of powertrain and vehicles for the off-road line are manufactured in the Osceola and Roseau facilities, respectively. Both the Victory and Indian motorcycle brands are American made with complete powertrains and vehicle assembly located in Osceola, Wisconsin, and Spirit Lake, Iowa, respectively.

Edgar Hetteen (later described by the Snowmobile Hall of Fame in St. Germain, Wisconsin as the father of the snowmobile), David Johnson, and Edgar's brother Allan Hetteen were partners in Hetteen Hoist and Derrick in Roseau, Minnesota. Edgar had dropped out of school after the eighth grade in 1934. David Johnson and company employees Paul Knochenmus and Orlen Johnson, who was the first person to ride a Polaris, decided to create a vehicle that could travel through snow. These vehicles' primary use was to make hunting locations more accessible. David Johnson and several employees created the prototype in 1954 while Edgar was on a business trip. Edgar returned to Roseau to discover the snow machine and was furious the employees had used their time and company resources on the machine. This first machine used a grain silo conveyor belt as a track, a Briggs and Stratton motor, and an old Chevy bumper for skis. Edgar was skeptical of its value, and the No. 1 sled was soon sold to Roseau lumberyard owner "Silver Pete" H.F. Peterson for $465 in order to meet company payroll.

However, the employees continued to focus on building snowmobiles and soon a second model was created, with Allan Hetteen leading the way; it was called the Polaris Sno Traveler. The first production model rolled off the assembly line in Minnesota in 1956. The original models weighed close to 1,000 lb (450 kg) and moved at a speed of about 20 mph (32 km/h). As Polaris snowmobiles gained sales traction, Edgar Hetteen became an advocate of the new product line. In order to promote the new snowmobile and prove its reliability and usefulness, in 1960 Edgar led a three-snowmobile, 1,200-mile trek across the Alaskan wilderness, starting from Bethel, Alaska. The trip took three weeks, and much of the time, Edgar struggled to maintain 10 mph over the snow. The Fairbanks Daily News-Miner put them on its front page. However, Edgar's absence caused problems for him with the Roseau bank's board of directors. Soon after completing the trip, Edgar left the company in June and started a competing company called Polar Manufacturing in Thief River Falls, Minnesota. The company name later changed to Arctic Enterprises; in the mid-1980s it filed for bankruptcy amid declining industry snowmobile sales with a recession and overproduction in a poor winter which continued the demise of many manufacturers. The company emerged from bankruptcy and continues on today as Arctic Cat.

Polaris began developing a smaller consumer-sized, front-engine snowmobile to compete with the Ski-Doo in the early 1960s. In 1964, Polaris released the Comet. However, the Comet soon ran into problems as it could not travel in all types of snow conditions. Polaris then recalled the sleds and quickly developed a new prototype to avoid bankruptcy. The new model, the 1965 Mustang, became a hit as a family snowmobile and boosted Polaris sales. Polaris continued to develop snowmobiles similar to this model throughout the 1960s–1970s, and went on to become one of the leaders in the snowmobile industry.

In the early 1980s, Polaris started creating an Indy style snowmobile with IFS and a wider stance. They continued with the Indy style sled in the 90s with the Storm, XLT, XCR, Ultra, RMK, and Trail lines, within the last few years Polaris has re-introduced the INDY model name. In 1985, Polaris introduced the Scrambler ATC and Trail Boss, which are considered to be the first American-made production all-terrain vehicles (ATV). In the early 1990s, Polaris introduced the Polaris Rocky Mountain King (RMK)- a snowmobile specific for mountain terrain. In May 2009, Polaris announced the creation of an On-Road Vehicle Division. The new division will be devoted to the growth of Victory motorcycles and other on-road products and brands. In 2010, Polaris introduced the Polaris Rush snowmobile which had a new suspension system and better trail handling capabilities. This snowmobile is also available with retro graphics on the Rush and Iq models. In late 2005, Polaris announced that it would purchase a portion of KTM Motorcycles. Through this venture KTM has developed their own ATV and Polaris has developed Sport ATVs which utilize the KTM 525 and 450 powerplants.

On May 21, 2010, Polaris announced that it was opening a new manufacturing plant in Mexico. The sister facility in Osceola, Wisconsin still remains in full operation. The opening of the Monterrey, Mexico facility is anticipated to save the company $30 million annually, with most of that savings coming from lower wages. The Monterrey facility has 3 assembly lines devoted to production of Ranger side-by-sides for global markets. The original intent of the Monterrey facility was to serve markets in the Southern US plus Mexico and North America.^{[citation needed]}
