Selwyn College is a constituent college of the University of Cambridge in England, United Kingdom.
The college was founded by the Selwyn Memorial Committee in memory of the Rt Reverend George Augustus Selwyn (1809–1878), who was an undergraduate and Fellow of St John's College, Cambridge and rowed on the Cambridge crew in the first Varsity Boat Race in 1829, and went on to become the first Bishop of New Zealand (1841–1868), and subsequently the Bishop of Lichfield (1868–1878).
Selwyn is less wealthy than some other traditional Cambridge colleges. In 2006 it had an estimated financial endowment of £22 million, and in 2004 fixed assets were worth £70 million. The college was ranked 16th out of 30 in an assessment of college wealth conducted by Varsity in November 2006.
Selwyn has, in recent times, excelled academically. In 2008, Selwyn was ranked first out of the 29 colleges which admit undergraduate students on the Tompkins Table (3rd in 2009, 4th in 2007, 6th in 2010, 7th in 2006).
