Swansea District before 1885 also known as Swansea District of Boroughs was a borough constituency. It was represented in the House of Commons of the Parliament of the United Kingdom. It elected one Member of Parliament (MP) by the first past the post system of election.

The seat was created for the 1832 general election, and abolished for the 1918 general election. Swansea District was a strongly Liberal constituency, dominated by the tinplate and steel industries, together with coal.

Upon its creation in 1832 it comprised five small boroughs: Swansea, Neath, Aberavon, Kenfig and Loughor. A small increase in their limits occurred in 1868.

In 1885, the seat was split into two, with the central part of Swansea borough forming the Swansea Town constituency, and the northern part of Swansea borough centred on Morriston, together with the four smaller boroughs, forming the seat Swansea District.

The first member after 1885 was Henry Vivian, who had represented Glamorgan county 1857–1885.
