The Halton Regional Police Service provides policing service for the Regional Municipality of Halton, which is located southwest of Toronto, in Ontario, Canada. Halton Region encompasses the city of Burlington and the Towns of Oakville, Milton and Halton Hills. As of July 2020, the Halton Regional Police Service has over 1,000 members, including 718 sworn police officers and approximately 302 civilian and volunteer members. The service is responsible for policing a population of approximately 610,000 people in an area covering 692 square kilometers.

The chief of police is the highest-ranking officer of the Halton Regional Police Service who governs the entire police service. Stephen J. Tanner began his term on September 1, 2012, and was sworn in on September 4. The chief reports to the seven-person Halton Police Services Board which is independent of the Municipal or Regional Council.

The Halton Regional Police Service was established in tandem with creating the Regional Municipality of Halton on January 1, 1974. It incorporated the former police services of Burlington, Oakville, Milton, and Halton Hills and first consisted of 205 officers and 45 civilians. The Ontario Provincial Police continued to police the remainder of the region until 1975 when the regional force had expanded to the point where it could assume responsibility for the entire area. In 2018 the new Halton Regional Police Service Headquarters at 2485 North Service Rd. W. was opened. The new facility totals 230,000 square feet in area.

The HRPS divides the region into five divisions (police stations) within three districts and one headquarters.
