Dublin City University (abbreviated as DCU) (Irish: Ollscoil Chathair Bhaile Átha Cliath) is a university situated on the Northside of Dublin in Ireland. Created as the National Institute for Higher Education, Dublin, it enrolled its first students in 1980 and was elevated to university status (along with the University of Limerick) in 1989 by statute. In September 2016, DCU completed the process resulting in the incorporation of three Dublin institutions: Church of Ireland College of Education; Mater Dei Institute of Education and St Patrick's College.

The university currently has 17,000 students and over 50,000 alumni. In addition the university has around 1,200 online distance education students studying through DCU Connected.

The University has been designated as a Changemaker Campus by Ashoka U for its work in social innovation in higher education.

Is ollscoil atá suite i dtuaisceart Bhaile Átha Cliath í Ollscoil Chathair Bhaile Átha Cliath nó OCBÁC (Béarla: Dublin City University nó DCU). Freastlaíonn thart ar 10,000 mac léinn uirthi. Is é uachtarán na h-ollscoile ná an tOllamh Ferdinand von Prondzyski. Bunaíodh an ollscoil i 1980 faoin ainm An Foras Náisiúnta um Ard-Oideachas, Baile Átha Cliath nó National Institute for Higher Education, Dublin (NIHE) as Béarla, mar chuid den Foras Náisiúnta um Ard-Oideachas, in éineacht le hinstitiúd eile i Luimneach. Tugadh stádas mar ollscoil don institiúd i 1989 agus athbhaisteadh é.
