The constituency of Gloucestershire was a UK Parliamentary constituency. After it was abolished under the 1832 Electoral Reform Act, two new constituencies, West Gloucestershire and East Gloucestershire, were created.

Gloucestershire was a constituency of the House of Commons of the Parliament of England, then of the Parliament of Great Britain from 1707 to 1800 and of the Parliament of the United Kingdom from 1801 to 1832. It was represented by two Knights of the Shire.

The constituency consisted of the historic county of Gloucestershire, excluding the part of the city of Bristol in the geographical county. Bristol had the status of a county of itself after 1373. Although Gloucestershire contained a number of other parliamentary boroughs, each of which elected two MPs in its own right for part of the period when Gloucestershire was a constituency, these were not excluded from the county constituency. Owning property within such boroughs could confer a vote at the county election. This was not the case, though, for Bristol.^{[citation needed]}

Roman numerals are used to differentiate MPs with the same name, who are not holders of a title with different succession numbers. It is not suggested that the people involved would have used Roman numerals in this way.
