The London School of Economics and Political Science, more commonly referred to as The London School of Economics or LSE is a college of the University of London in London, England. It was founded in 1895, and officially joined the federal University in 1900 as the Faculty of Economics, beginning to issue its degrees from 1902. Today it remains a specialist single-faculty constituent college of the University, the only such institution in Britain. Located on Houghton Street in Westminster, off the Aldwych and next to the Royal Courts of Justice and Temple Bar, it describes itself as "the world‘s leading social science institution for teaching and research".

The School is a member of the elite Russell Group, the European University Association, Association of Commonwealth Universities, the Community of European Management Schools and International Companies, The Association of Professional Schools of International Affairs and Universities UK as well as the Golden Triangle of British Universities, and most recently the secretive 'super-elite' 'G5 Group' of Britain's five leading universities. In 2006, the LSE joined the 'U8' group, a worldwide student network of universities, linking universities from across the world.

According to The Guardian newspaper, the London School of Economics has a"reputation that in this country only Oxbridge can beat".
