Papa Urban I alikuwa Papa kuanzia tarehe 14 Oktoba 222 hadi kifo chake tarehe 23 Mei 230. Alitokea Roma, Italia. Alimfuata Papa Kalisto I akafuatwa na Papa Ponsyano. Urban I ni Papa wa kwanza ambaye tarehe zake zina hakika ya kihistoria. Inaonekana hakukuwa na dhuluma za serikali wakati wa Upapa wake, lakini alipaswa bado kupambana na farakano la Hipoliti wa Roma. Tangu kale anaheshimiwa kama mtakatifu, hasa tarehe 19 Mei, sikukuu yake.
