Bangor University (Welsh: Prifysgol Bangor) is a Welsh university in the city of Bangor in the county of Gwynedd in North Wales. It received its Royal Charter in 1885 and was one of the founding member institutions of the former federal University of Wales.

It was officially known for most of its history as the University College of North Wales (UCNW), and later as the University of Wales, Bangor (UWB) (Welsh: Prifysgol Cymru, Bangor). From September 2007 it became known as Bangor University, having become independent from the federal University of Wales.

In 2012 Bangor was ranked 251st among the world's top universities. According to the Sunday Times University Guide 2012, it is rated top in Wales for teaching excellence and is among the top 15 universities in the UK in this category.

Bangor has a strong research base across a spectrum of academic disciplines engaging in research at national and international levels. The University provides strong support for research activities including encouraging links with commercial and industrial bodies in the UK and overseas. The University also aims to be responsive to local and regional needs and is particularly conscious of its North Wales location and role as a research resource and a training base for Wales.

Research is carried out either directly in the Schools or in Research Centres and Institutes associated with one or more School.
