Alcatel-Lucent S.A. (French pronunciation: ) was a French global telecommunications equipment company, headquartered in Boulogne-Billancourt, France. It was formed in 2006 by the merger of France-based Alcatel and U.S.-based Lucent, the latter being the successor of AT&T's Western Electric.
On 3 November 2016, Nokia completed the acquisition of the company and it was merged into their Nokia Networks division. Bell Labs was still maintained as an independent subsidiary of Nokia. The Alcatel-Lucent brand has been replaced by Nokia, but it still survives under Alcatel-Lucent Enterprise (ALE), the enterprise division of Alcatel-Lucent that was sold to China Huaxin in 2014.
