The Glasgow Police Act 1800 was an act of Parliament passed by the Parliament of Great Britain, which established a professional police force for the city of Glasgow. Under the act, this police force was placed under the control of the Lord Provost, three magistrates and nine elected commissioners.^[1] The force was supported financially by a rate levied by the City Council on houses and businesses; the lack of such a levy had frustrated the previous attempt at having a professional police presence in the city.^[1]

The act was a forerunner of similar acts of Parliament establishing police forces in other Scottish cities and burghs, culminating in the Police (Scotland) Act 1850 (13 & 14 Vict. c. 33) and the General Police and Improvement (Scotland) Act 1862 (25 & 26 Vict. c. 101).^[1]

As well as making provision for the establishment of a police force, the act also authorised the annexation of ninety-six acres of land surrounding the city.^[2]
