Leeds South is a parliamentary constituency in the city of Leeds, West Yorkshire, which returns one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom. The constituency existed from 1885 to 1983 and was recreated in 2024 following the 2023 Periodic Review of Westminster constituencies.

In the 2024 general election, the seat was won by Hilary Benn of the Labour Party, who serves as Secretary of State for Northern Ireland in the government of Keir Starmer. Benn had represented Leeds Central, the main predecessor of Leeds South, since 1999.

Leeds South was the seat of the former Leader of the Labour Party, the late Hugh Gaitskell, and the former Home Secretary Merlyn Rees.

The constituency was created in 1885 by the Redistribution of Seats Act 1885, and was first used in the general election of that year. Leeds had previously been represented by two MPs (1832–1868) and three MPs (1868–1885). From 1885 it was represented by five single-member constituencies: Leeds Central, Leeds East, Leeds North, Leeds South and Leeds West. The constituencies of Morley, Otley and Pudsey were also created in 1885.

The constituency was abolished for the 1983 general election. It was then largely replaced by the new Morley and Leeds South constituency. After the 1983 general election Leeds was represented by the constituencies of Leeds Central, Leeds East, Leeds North East, Leeds North West, Leeds West and Morley and Leeds South. There were also constituencies of Elmet (created 1983) and Pudsey.

Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat was re-established for the 2024 general election, formed primarily from the (abolished) constituency of Leeds Central, but excluding the city centre, and including a small part of Leeds East and a very small part of Morley and Outwood. The notional 2019 result for the new seat was Labour.

1885–1918: The Municipal Borough of Leeds wards of East Hunslet, South, and West Hunslet, and part of Bramley ward.

1918–1950: The County Borough of Leeds wards of Holbeck and West Hunslet, and part of New Wortley ward.

1974–1983: The County Borough of Leeds wards of Beeston, East Hunslet, Holbeck, Middleton, and West Hunslet.
