Space Cadets was a British comedy panel game broadcast on Channel 4 in 1997. It was presented by "High Commander" Greg Proops with Bill Bailey and Craig Charles as the "Space Captains" (captains of the two teams). It ran for just one series with 10 episodes.

Like the BBC's Have I Got News for You, the contestants were celebrities and the show was played mainly for laughs. Bestselling author Terry Pratchett once appeared as a guest. When the contestants were asked who was Britain's most shoplifted author, Pratchett immediately answered "I am!" which was the correct answer. (The other contestants and Proops all immediately pulled out "shoplifted" copies of Pratchett's books, one of which Pratchett proceeded to sign.)
