University College London (UCL) is a public research university in London, England, and a constituent college of the federal University of London. It is the third largest university in the United Kingdom by total enrollment and ranked as one of the top universities nationally and internationally.

Established in 1826 as London University by founders inspired by the radical ideas of Jeremy Bentham, UCL was the first university institution to be established in London, and the first in England to be entirely secular and to admit students regardless of their religion. UCL also makes the contested claims of being the third-oldest university in England and the first to admit women.

UCL ranks highly in national and international league tables and its graduates rank among the most employable in the world. There are at least 29 Nobel Prize winners and 3 Fields medalists amongst UCL’s alumni and current and former staff.
