IHG will also aid the London Organising Committee of the Olympic Games and Paralympic Games (LOCOG) by supplying experienced personnel to assist in the planning and operation of the Athletes' Village.
Holiday Inn, which is currently undergoing a £600m rebranding process, will supply team members to work with LOCOG's accommodation and protocol teams in the lead up to the Games in 2012.
Holiday Inn, along with other hotels in the IHG stable, will also provide accommodation and meeting rooms for LOCOG and its partners as it builds towards the Games.
Andy Cosslett, chief executive of IHG, said: "With the £600m relaunch of Holiday Inn well underway, being selected to welcome guests from LOCOG and its partner organisations to our hotels is perfect timing.
London 2012 chairman Sebastian Coe added: "The global expertise of Holiday Inn in welcoming visitors and meeting customer needs will be vital between now and 2012."
