Anglia Ruskin University (ARU) is a public research university in the region of East Anglia, United Kingdom. Its origins date back to the Cambridge School of Art (CSA), founded in 1858 by William John Beamont, a Fellow of Trinity College at the University of Cambridge. The institution became a university in 1992 and was renamed after John Ruskin, the Oxford University professor and author, in 2005. Ruskin delivered the inaugural speech at the Cambridge School of Art in 1858. ARU is classified as one of the "post-1992 universities." The university's motto is in Latin: Excellentia per societatem, which translates to Excellence through partnership in English.

As of 2022, Anglia Ruskin had 35,195 students. ARU has six campuses across the south-eastern portion of the United Kingdom in Cambridgeshire, Essex, and Greater London.
