International Power PLC (LSE: IPR) is an international electricity generator formed in 2000 by the demerger of National Power. It is headquartered at Senator House, 85 Queen Victoria Street in the City of London. It is listed on the London Stock Exchange and, after a two and a half year absence, it rejoined the FTSE 100 Index in March 2005.

In August 2010 the company announced a tie-up with GDF Suez, whereby that firm's international assets will be transferred to International Power, with a new company being formed - New International Power. This company would be 70% owned by GDF Suez and 30% owned by existing International Power shareholders. The proposal requires the approval of the shareholders, although this is expected by end 2010 or early 2011.

In 2000 National Power demerged its UK businesses as Innogy with the remainder of the business being renamed International Power. The Company was first listed on the London Stock Exchange on 2 October 2000. In August 2010 International Power and French utility GDF Suez joined to form New International Power.
