List of Countdown champions

This is a list of champions on the game show Countdown.

These are players who have won up to eight games and scored enough points to qualify for their series' finals.

Here, they were one of eight contestants invited back to compete in a knockout tournament to decide who will become the series champion.

Series 54 began four months later on 31 October 2005 and, having started very late in the year, was extended to last until 26 May 2006.

Up until Series 83, champions were also awarded the complete leather-bound set of the Oxford English Dictionary (although the Series 31 champion, David Acton, turned the prize down due to his strict veganism and instead opted to take it in CD-ROM form, donating the sizeable cash difference to a local school).
