The Queensland Police Service (QPS) is the law enforcement agency responsible for policing the Australian state of Queensland. In 1990, the Queensland Police Force was officially renamed the Queensland Police Service and the old motto of "Firmness with Courtesy" was changed to "With Honour We Serve". The headquarters of the Queensland Police Service is located at 200 Roma Street, Brisbane.

The 1980s was a turbulent period in Queensland Police history. Terry Lewis, a former Queensland Police commissioner, was convicted and jailed for 10 years for corruption and forgery as a result of the Fitzgerald Inquiry.

Commissioner Robert Atkinson, APM is the present Commissioner of the Queensland Police Service.

Queensland as a state did not exist until 6 June 1859. The area now called Queensland was known as North Eastern New South Wales. The colony would have been under the jurisdiction of the New South Wales Police Force up until Queensland established its own police force.

The Queensland Police were established on 1 January 1864 and started operations with approximately 143 employees, including the first Commissioner of Police D.T. Seymour. The service had four divisions: Metropolitan Police, Rural Police, Water Police, and Native Police. Bicycles were introduced in 1895. At the turn of the century there were 845 men and 135 Aboriginal trackers at 256 stations in Queensland.

Coordinates: 23°0′S 143°0′E / 23°S 143°E / -23; 143 Queensland is the second-largest and third-most populous state of Australia, located in the northeast of the country. It is bordered by the Northern Territory, South Australia and New South Wales to the west, southwest and south respectively. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. Queensland has a population of 4,580,700, concentrated along the coast and particularly in the state's South East. The state is the world's sixth largest subnational entity, with an area of 1,852,642 km2. The capital and largest city in the state is Brisbane, Australia's third largest city. Referred to as the 'Sunshine State', Queensland is home to 10 of Australia's 30 largest cities and is the nation's third largest economy.

Queensland was first occupied by Indigenous Australians and Torres Strait Islanders, who arrived at least 40,000 years ago. The first European to land in Queensland was Dutch navigator Willem Janszoon in 1607. In 1770, Lieutenant James Cook claimed the east coast of Australia for the Kingdom of Great Britain. The colony of New South Wales was founded in 1788 by Governor Arthur Phillip at Sydney; New South Wales at that time included all of what is now Queensland, Victoria and Tasmania. Queensland was explored in subsequent decades until the establishment of a penal colony at Brisbane in 1824 by John Oxley. Penal transportation ceased in 1839 and free settlement permitted in 1842. Queensland was separated from New South Wales, forming a self-governing colony, on 6 June 1859, a date now celebrated state-wide as Queensland Day. Queensland achieved statehood with the Federation of Australia on 1 January 1901.
