The men's 800 metres at the 2007 World Championships in Athletics was held at the Nagai Stadium on 30, 31 August and 2 September.
The 800 metres, or 800 meters, is a common track running event. It is the shortest common middle-distance running event. The 800 metres is run over two laps of the track and has been an Olympic event since the first games in 1896. During indoor track season the event is usually run on a 200-metre track, therefore requiring four laps.
The 11th World Championships in Athletics, under the auspices of the International Association of Athletics Federations (IAAF), were held at Nagai Stadium in Osaka, Japan from 24 August to 2 September 2007. 200 of the IAAF's 212 member federations entered a total of 1,978 athletes, the greatest number of competitors at any World Championships to date. Sarah Brightman, the world's best-selling soprano, performed her single Running at the opening ceremony.
