2000 Today is an internationally broadcast television special that was aired to commemorate the beginning of the Year 2000. This programme included New Year's Eve celebrations, musical performances, and other features from participating nations.

Most international broadcasts such as the Olympic Games coverage originate from a limited area for worldwide distribution. 2000 Today was rare in that its live and taped programming originated from member countries and represented all continents.

2000 Today was conceived as part of the Millennium celebrations, given the numerical significance of the change from 1999 to 2000. 2000 Today was commissioned by the BBC as one of the five main millennium projects that were broadcast across TV, radio and online services throughout 1999 and 2000.

Most nations that observe the Islamic calendar were not involved in 2000 Today. However, a few predominantly Muslim nations were represented among the programme's worldwide broadcasters such as Egypt (ERTU) and Indonesia (RCTI). Africa was minimally represented in 2000 Today. The only participating nations from that continent were Egypt and South Africa. Portugal-based RTP África distributed the programme to some African nations.

Antarctica was mentioned on the programme schedule, although it was unclear if 2000 Today coverage was recorded or live.

The programme was produced and televised by an international consortium of 60 broadcasters, headed by the BBC in the United Kingdom and WGBH in Boston, United States. The editorial board also included representatives from ABC (Australia), CBC (Canada), CCTV (China), ETC (Egypt), RTL (Germany), SABC (South Africa), TF1 (France), TV Asahi (Japan), TV Globo (Brazil) and ABC (USA). The BBC provided the production hub for receiving and distributing the 78 international satellite feeds required for this broadcast. The idents for the programme were designed in the UK by Lambie-Nairn and the BBC for use by all the participating broadcasters taking part in the event. The linking theme throughout all the idents and promotions was a distinctively shaped stone engraved with the year 2000. The themes were: desert, fire, ice, lasers and water; plus a special BBC News ident.

Up to 5,000 staff worked on 2000 Today, 1,500 of them in BBC Television Centre in West London, where all eight television studios were used during the 28-hour broadcast. Each participant financed and produced its own contributions and shared the core costs proportionately to its size and wealth. It is estimated to have cost $6 million to produce and broadcast. At the time, technicians at Radio-Canada were on strike. Transmissions were seen as scheduled, but using only the main feed from the BBC, with a French voice-over. Also, as a consequence, 2000 footage from Canada was scarce on SRC's presentation, while footage from Quebec was not available at all worldwide (though the CBC did manage to get the only Quebec coverage on their own network—a video shot of midnight fireworks in Hull, Quebec, shot from Ottawa, Ontario).

2000 Today was nominated for "Best Visual Effects and Graphic Design" at the 2000 British Academy Television Craft Awards.
