Missouri Counties

Missouri has one hundred and fourteen counties and one independent city. St. Louis City is separate from St. Louis County and is referred to as a "city not within a county." Following the Louisiana Purchase and the admittance of Louisiana into the United States in 1812, five counties were formed out of the Missouri Territory at the first general assembly. Most subsequent counties were apportioned from these five original counties.
