西汉高帝公元前206年，置城阳县，属汝南郡，①治所在今河南省信阳市东北。②
西汉末23年废。③

注：
	① 《汉书》卷二十八上：“汝南郡，……成阳，侯国。莽曰新利。定陵。高陵山，汝水出，东南至新蔡入淮，过郡四，行千三百四十里。”（北京：中华书局，1962年，第1562页。）
	② 《中国历史地名辞典》：“成阳县，西汉置，治所在今河南省信阳市东北。东汉废。南朝梁复置。隋废。”（南昌：江西教育出版社，1988年，第293页。）
③ 县废时间不详，《后汉书》郡国志中已无“成阳”记载，故作西汉亡年23年为县废之年。    ]]>  </source-note>  <source-uri>      </source-uri></placename>
