Joseph Quinn (c. 1861 – July 5, 1887) was a New York clerk, amateur wrestler and murder victim of Danny Lyons, a co-leader of the Whyos street gang.
Although reportedly described as a pimp and rival Five Points thug, Quinn is described in newspaper accounts as "a respectable young man, who for nine years past has been employed at the Cotton Exchange."
He would again face O'Brien in a catch-as-catch-can match, with each man gaining a pinfall before a draw was declared after wrestling another 10 minutes for the deciding third fall at an exhibition held by the New York Athletic Club on December 10, 1885.
Although his wound was judged to be fatal upon an earlier examination by Dr. Pfeiffer, officials of Bellevue Hospital were criticized for the difficulty and delay in calling an ambulance.
More than a half an hour had passed as Quinn lay in the drug store when a young man entered the hospital to ask if an ambulance had been sent yet.
