Oadby is a town in the borough of Oadby and Wigston in Leicestershire, England. Oadby is a district centre 4 miles (6.4 km) south-east of Leicester on the A6 road. Leicester Racecourse is situated on the border between Oadby and Stoneygate. The University of Leicester Botanical Garden is in Oadby. Oadby had a population of 23,849 in 2011, and like its neighbour Wigston is made up of five wards. The Borough of Oadby and Wigston is twinned with Maromme in France, and Norderstedt in Germany.

There has been a habitation in Oadby since an Anglian settlement in the early Anglo-Saxon period. Though the name Oadby is Danish (meaning "Outi's dwelling") it must have existed long before the Danish invasions as is shown by the existence of a pagan Anglian cemetery. The original Anglian name has been lost. In 1760, on Brocks Hill, evidence of an Anglian burial ground was discovered. The Middle Angles came under the rule of the kings of Mercia and were later conquered by the Danish invaders. Oadby is one of seventy Danish settlements in Leicestershire ending with "-by", which means village or settlement. Its name probably came from Old Norse Auðarbýr = "Auði's settlement". Danish rule continued until 920, when King Alfred the Great won his battles against the Danes: the Oadby area is supposed to be the site of at least one of these battles.

In the Domesday Book, 1086, Oadby's name was recorded as Oldebi. Other early forms are Oladebi, Outheby (Feet of Fines, 1199), Onderby and, finally, Oadby. When King Harold had been defeated, William the Conqueror gave Oadby to Hugh de Grandmesnil, Governor of Leicestershire, who founded the parish church of Oadby on the site of the present St Peter's Church. The tenants of the manor of Oadby were Roger who held one and half carucates, and Countess Judith who held 9 carucates and 2 bovates, and 30 acres of meadow. On the Countess's land were 46 socmen, eleven bordars and three serfs; two carucates were let to Robert de Buci. The manor was held in 1444 by William Ferrers; in 1457 it was held by William Grey, Lord Ferrers of Groby. In 1541 the manor was held by John Waldron; his successor John Waldron sold it in 1629 to Sir John Lombe. In 1831 the main landed proprietors were the trustees of the late George Wyndham (patrons of the vicarage), George Legh Keck (lord of the manor) and Thomas Pares.

Oadby remained a small settlement until the late 19th century when it became a fashionable suburb for the businessmen of Leicester, such as the factory owners of Leicester's shoe and stocking manufacturers. Many substantial houses were built in Oadby, some of which are now used by the University of Leicester.

Stoughton Road in Oadby contains two sets of houses of historical interest. Some of the Framework Knitters Homes date back to 1909, while the North Memorial Homes, financed by Sir Jonathan North (former Mayor of Leicester), were built in 1927 and opened in the same year by the Prince of Wales. As well as a series of houses, the North Memorial Homes site also houses the North Memorial Hall, built in a neo-Georgian style, which has been leased to Oadby Evangelical Free Church since 1974.

In the late 19th century Oadby town centre was focused along Leicester Road, The Parade and London Road. The oldest properties and locations can be found at the Wigston Road, London Road junction through to the Glen Road (A6) junction. Some of the 19th century buildings that remain are the cottages and shops (including Wilson B Ragg Butchers & Gingerbread Cottage bakers) along London Road through to Glen Road.

Expansion of Oadby took place rapidly in the 20th century and was still continuing in 2017. Many residential developments have been constructed, and the population in 2011 reached 23,849.

In the early 20th century, the Travellers Rest (located near to the London Road Glen Road junction) was torn down in 1939 and replaced by The Oadby Owl on a neighbouring site. Both inns were run by Walter Cufflin (a descendant of James Hawker).
