Kelly's Directory (or more formally, the Kelly's, Post Office and Harrod & Co Directory) was a trade directory in England that listed all businesses and tradespeople in a particular city or town. It was also a general directory of postal addresses of local gentry, landowners, charities, and other facilities.
The originator of the directory was Frederic Festus Kelly, who in 1835 or 1836 had become chief inspector of letter-carriers for the inland or general post office.
