Allerton is a suburb of Liverpool, in Merseyside, England. It is located 3 miles (4.8 km) southeast of Liverpool city centre, bordered by Mossley Hill, Woolton, Hunts Cross and Garston.

Historically a part of Lancashire, Allerton has a number of large houses in the prestigious Calderstones Park area, with mainly 1930s semi-detached housing around the shopping area of Allerton Road. Allerton is paired with nearby Hunts Cross to form the Allerton and Hunts Cross city council ward.

In the Domesday Book it appears as Alretune meaning 'the alder enclosure', derived from the Old English alr 'alder' and tún 'enclosure or village'.

Allerton was made an urban district by the Local Government Act 1894, and added to the county borough of Liverpool on 9 November 1913.

In the past ten years many new bars and restaurants have opened in Allerton - mainly on Allerton Road and is a popular place for pubgoers.

Allerton is served by two railway stations: Liverpool South Parkway on the border of Allerton and Garston (it is the train track running from Liverpool South Parkway from the old Allerton Station that separates Garston from Allerton), and West Allerton on Booker Avenue. Both stations offer services to Liverpool city centre and Manchester, but Liverpool South Parkway also has services to Southport and Hunts Cross (on the Merseyrail Northern Line) and also the fast service to Birmingham. The former Allerton railway station has been replaced with Liverpool South Parkway, although as the platforms are in use as this new station, it does, in effect, still exist.

Merseyside ( /ˈmɜrzisaɪd/) is a metropolitan county in North West England, with a population of 1,365,900. It encompasses the metropolitan area centred on both banks of the lower reaches of the Mersey Estuary, and comprises five metropolitan boroughs: Knowsley, St Helens, Sefton, Wirral, and the city of Liverpool. Merseyside, which was created on 1 April 1974 as a result of the Local Government Act 1972, takes its name from the River Mersey.

Merseyside spans 249 square miles (645 km²) of land which border Lancashire (to the north-east), Greater Manchester (to the east), and Cheshire (to the south and south-west); the Irish Sea is to the west. North Wales is across the Dee Estuary. There is a mix of high density urban areas, suburbs, semi-rural and rural locations in Merseyside, but overwhelmingly the land use is urban. It has a focused central business district, formed by Liverpool City Centre, but Merseyside is also a polycentric county with five metropolitan districts, each of which has at least one major town centre and outlying suburbs. The Liverpool Urban Area is the seventh most populous conurbation in the UK, and dominates the geographic centre of the county, while the smaller Birkenhead Urban Area dominates the Wirral Peninsula in the south.
