Harlaxton is a suburb of Toowoomba, Queensland, Australia, located 4 kilometres (2 mi) north of the city centre. At the 2011 Australian Census the suburb recorded a population of 2,689.
The name originates from Harlaxton House, probably named for Harlaxton in Lincolnshire, England, and built in 1869 in what is now Munro Street as the residence of Francis Thomas Gregory. Gregory was an explorer in Western Australia, before moving to Queensland in 1862, serving as Commissioner of Crown Lands and an appointed Member of the Legislative Council from 1874 until his death in 1888. The home was later used as the summer residence for Lord Lamington who served as Governor of Queensland from 1896 until 1901. A railway station was built for his use at the site. The house is in a deteriorating condition, partly due to blasts from the neighbouring quarries.
