Renfrewshire was a county constituency of the House of Commons of the Parliament of Great Britain from 1708 until 1801 and of the Parliament of the United Kingdom from 1801 to 1885.

The British parliamentary constituency was created in 1708 following the Acts of Union, 1707 and replaced the former Parliament of Scotland shire constituency of Renfrewshire.

The constituency covered the county of Renfrewshire, minus the parliamentary burgh of Renfrew throughout the 1708 to 1885 period, and minus the parliamentary burgh of Port Glasgow and the Paisley and Greenock constituencies from 1832 to 1885.

The burgh of Renfrew was a component of Glasgow Burghs until 1832, when it became a component of Kilmarnock Burghs. Port Glasgow became a parliamentary burgh in 1832, and another component of Kilmarnock Burghs.

The constituency elected one Member of Parliament (MP) by the first past the post system until the seat was abolished in 1885.^{[1] [2] [3] [4] [5]}

In 1885 the Renfrewshire constituency area was divided into two new constituencies: Renfrewshire Eastern and Renfrewshire Western.
