Telefonica O2 plc (known as O2 or before March 2005 as mmO2) is a British telecommunications company specializing in mobile telephony, originally part of the BT Group and owned since 2005 by the Spanish operator Telefónica. The firm is headquartered in Slough, with major offices in Bury, Glasgow, Leeds, and Preston Brook.

Launched in 1985 as Cellnet, O2's UK operations were a joint venture between BT Group (60%) and Securicor (40%). In 1993, Cellnet launched GSM services, and in 1999, Securicor sold its shares in O2 to BT: O2 was renamed BT Cellnet. BT Cellnet was integrated into BT Mobile.

O2 was created when BT separated from its cell phone business. The BT Cellnet brand was renamed O2, the chemical symbol for oxygen.

In May 2020, Telefónica and Liberty Global announced the merger of O2 and Virgin Media in the United Kingdom in a deal valuing the combined entity at nearly $38 billion, including debt. Both companies will have a 50% stake in the combined entity.
