An invented name, chosen in the 1930s as a play on neighbouring Kingsbury.
Local people were asked for ideas when the new suburb and station needed a name; the builder, Percy Harold Edwards, ran a newspaper competition. The first choice, Kingsbury Downs, came from an earlier name for the fields, Hungry Downs, but was rejected in favour of Queensbury. Kingsbury means the manor of the king. The station opened in 1934.
