Cambridge University Press (known colloquially as CUP) is a publisher given a Royal Charter by Henry VIII in 1534, and one of the two major university presses in the UK (the other being Oxford University Press).

It published its first book in 1584, and has published at least one book every year since then, making it the oldest publishing and printing house in the world. It is both an academic and educational publishing house, a printing factory, and the printer for official documents for the University of Cambridge.

The Press is now a global organisation with a regional structure operating in the Americas, in UK/Europe/Middle-East/Africa, and in Asia-Pacific. Headquartered in Cambridge UK, the company has warehousing centres in Cambridge, New York, Melbourne, Madrid, Cape Town, São Paulo and Singapore, with offices and agents in many other countries.

Its publishing output includes major ELT courses and learning aids such as dictionaries.
