The University of Wales Trinity Saint David is a collegiate university operating on three main campuses in South West Wales: in Carmarthen, Lampeter, and Swansea. The university also has a fourth campus in London, England.

The university came into existence through the merger of the two oldest higher education institutions in Wales, the University of Wales, Lampeter and Trinity University College in 2010, under Lampeter's royal charter of 1828. In 2011, it was announced that the University of Wales would also be merged into Trinity Saint David. On 1 August 2013 the university merged with Swansea Metropolitan University.

The Chancellor of the University of Wales — and therefore Trinity Saint David — is HRH, The Prince of Wales, the President of Trinity Saint David is R. Brinley Jones and the Vice-Chancellor is Medwin Hughes.
