Square Enix Limited, doing business as Square Enix Europe, is a British publisher of video game software wholly owned by Square Enix. Square Enix Europe has its head office in the 240 Blackfriars Road in London Borough of Southwark, London.

Square Enix Europe was originally the now-defunct Eidos plc, when it was the holding company for the Eidos group of companies, including United Kingdom video game publisher Eidos Interactive, which is responsible for the Just Cause, Tomb Raider and Hitman games, among others. It is the successor to Square Enix Ltd. and Eidos Interactive and will distribute and publish both Eidos and Square Enix's games under the Square Enix label. After the takeover of Eidos plc, Namco Bandai Partners handed over the Australian distribution rights of Eidos to Ubisoft Australia, which have a distribution deal with Square Enix.

After a successful takeover by Square Enix which came into effect on 22 April 2009, shares of Eidos officially de-listed on 21 April 2009 a day before the takeover. The name Eidos plc ceased to be used following a reorganisation of the Eidos Group, after which all previous Eidos properties were published under Square Enix and Eidos Interactive now as a part of Square Enix Europe.
