Ealing, Southall (also Ealing Southall) is a constituency^{[n 1]} created in 1983 and represented in the House of Commons of the UK Parliament since 2007 by Virendra Sharma of the Labour Party.^{[n 2]}

The constituency has relatively good road and rail transport, and numerous small to medium-size green spaces,^[2] and has had as many as three tube stations at its eastern extremes of its boundaries. Southall and Norwood Green, forming the western bulk of the seat, feature a high British Asian proportion of the population since the 1960s. British Indian ethnicity is the largest single ethnic group. British Asians account for 51% of the population, as at the 2011 census,^[3] the majority of this minority is of Indian ethnicity (29.6%), with significant Hindu and Muslim populations, with the highest number of Sikh residents in any constituency in Britain at over 20%.^[4] The Afro-Caribbean community amounts to 8% according to the latest census statistics. The seat has generally modest incomes and the vast majority of housing is modest terraced, semi-detached or mid-rise 20th century blocks of flats. The east of the seat is formed by Hanwell and West Ealing.

The seat has been served by three successive Labour Party MPs since its inception in 1983, with majorities ranging between 13.8% and 49% of the vote; the latter was achieved in 2017, which was not a landslide year for the party. The length of tenure and size of majorities mean that practical analyses consider Ealing Southall a safe seat. The 2015 result made the seat the 25th safest of Labour's 232 seats by percentage of majority.^[6] The larger predecessor seat, created in 1945, was held by Labour throughout its existence.
