Pembrokeshire (Welsh: Sir Benfro) was a parliamentary constituency based on the county of Pembrokeshire in Wales. It returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected by the first past the post system.

The Laws in Wales Act 1535 (26 Hen. VIII, c. 26) provided for a single county seat in the House of Commons for each of twelve historic Welsh counties (including Pembrokeshire) and two for Monmouthshire. Using the modern year, starting on 1 January, these parliamentary constituencies were authorised in 1536. In practice, the first known Knights of the Shire from Wales (as Members of Parliament from county constituencies were known before the nineteenth century) may not have been elected until 1545.

The Act contains the following provision, which had the effect of enfranchising the shire of Pembroke.

And that for this present Parliament, and all other Parliaments to be holden and kept for this Realm, one Knight shall be chosen and elected to the same Parliaments for every of the Shires of Brecknock, Radnor, Mountgomery and Denbigh, and for every other Shire within the said Country of Dominion of Wales;

During this period the seat was largely held by the Conservatives who held off the Liberal challenge which was so apparent in other parts of Wales. When Lord Emlyn inherited the title Earl of Cawdor in 1860 the seat was held until 1866 by George Lort Phillips. He was succeeded by James Bevan Bowen of Llwyngwair who stood down in favour of Sir John Scourfield in 1868. Scourfield died in 1876 and Bowen once again became the county member. In 1880, however, he was defeated by William Davies and the Liberals held the seat until 1918.
