Portobello House (also known formerly as Portobello Hotel) is a building on the bank of the River Ogmore, about half a mile up from the sea, near the estuary at Ogmore-by-Sea, western Vale of Glamorgan, southeast Wales, on the country border with Bridgend County Borough.

A community history reports that "At one time, it was only possible to buy drinks on a Sunday throughout Wales if you could prove to the innkeeper that you had travelled three miles or more".

[2][3] The Portobello Hotel served well as a post-practice social gathering place for shooters at the Glamorgan Artillery, as it was conveniently "the required distance".

[2][4] Also walkers in the countryside seeking to cross the River Ogmore would not be able to cross if the tide was in, and a Mr. Prosser from the Portobello could be relied upon to ferry across the river in "his little flat-bottomed home-made boat for a small fee.

"[2] The Portobello House has been owned for decades by Dawn Clarenda Mary Llewellyn, a former medical professional.
