Derbyshire County Cricket Club in 1939 was the last cricket season before World War II, when the English club Derbyshire had been playing for sixty-eight years.
Derbyshire played 28 matches in the County Championship, one against Oxford University and one against the touring West Indians.
They won eleven matches altogether, ten in the County Championship.
Denis Smith scored most runs and Bill Copson took most wickets.
Nearly all the players had been members of the 1936 championship winning team and the only player to make his debut was Cliff Gladwin whose low scores and failure to take a wicket gave little inkling that he would turn out to be Derbyshire's main wicket-taker in the years after World War II.
