Joseph Jackson Davenport (1849 – 1921) was a lawyer, realtor and Mayor of Kansas City, Missouri in 1889. He moved to Kansas City from his native Saint Louis in about 1873, joining "the pork-packing business with J. E. McKenzie," and after his term as mayor entering real estate. Following his term a new city charter was implemented and terms were extended to two years.

Davenport had a legendary encounter with Kansas City Star publisher William Rockhill Nelson in which Davenport was alleged to have gone to the publisher's office (with or without a gun according to various tellings) to settle a squabble "man to man." Managing Editor T.W. Johnston, City Editor Ralph Stout, Editorial Writer William Allen White and a telegrapher named Phillips came to Nelson's aid, threw Davenport down a flight of stairs with Davenport saying "Drop the cuspidor, Ralph Stout! Put that spittoon down!" Nelson was reported to have said. "The Star never loses!"^[1]
