Truro was the name of a parliamentary constituency in Cornwall represented in the House of Commons of England and later of Great Britain from 1295 until 1800, then in the Parliament of the United Kingdom from 1801 to 1918 and finally from 1950 to 1997. Until 1885 it was a parliamentary borough, electing two members of parliament (MPs) by the plurality-at-large system of election; the name was then transferred to the surrounding county constituency, which elected a single Member by the first past the post system. In 1997, although there had been no changes to its boundaries, it was renamed as Truro and St Austell, reflecting the fact that St Austell by then had a larger population than Truro.

1295–1885: The parliamentary borough before 1832 consisted of only part of the town (not yet a city) of Truro. It was extended by the Great Reform Act of 1832 to contain the whole town, namely St Mary parish and parts of the parishes of St Kenwyn and St Clement, but nothing beyond that.

1885–1918: The county division took in a considerable area of South-West Cornwall, including (as well as Truro itself) the town of Helston. Also, in the towns of Falmouth and Penryn, which together constituted a borough constituency adjoining Truro, the freeholders could vote in the Truro division. This constituency was abolished in 1918, being divided between the new or revised Penryn and Falmouth, St Ives and Camborne county constituencies.
