Honorat Koźmiński (16 October 1829 – 16 December 1916), born Florentyn Wacław Jan Stefan Koźmiński, was a Polish priest and professed member from the Order of Friars Minor Capuchin who went on to establish sixteen religious congregations. He was a teacher before reinvigorating clandestine religious orders that the Russian Empire had suppressed during their occupation of Poland. He collaborated with a number of individuals in this venture and he publicised the Third Order of Saint Francis to people.
