User:CountdownCrispy/List of Dictionary Corner celebrity guests on Countdown

This is a list of Dictionary Corner celebrity guests on the British game show Countdown. Along with a lexicographer, Dictionary Corner houses a celebrity guest, sometimes called the "Dictionary Dweller", who contributes words and also provides a short interlude at the end of the first section of the show.

This list is alphabetically ordered by surname, and includes information on all appearances made by a celebrity in Dictionary Corner: on regular daily editions of Countdown; on special editions produced to be aired at short notice, for example if scheduled sport coverage finishes early; on the short prime-time spin-off series "Celebrity Countdown"; and on the one-off programme "Countdown at Christmas".
