刘宋泰始470年置，属宋安郡，①治所在今河南省信阳市东北。② 
隋589年，县随宋安郡废。③ 

注：
	① 《魏书》卷一〇六中：“宋安郡刘彧置，魏因之。领县二。乐宁，有成阳关、鸡头山。东随，有黄岘关、长平山庙。”（北京：中华书局，1974年，第2568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。）又，《魏书》卷一〇六中：“宋安郡刘彧置，魏因之。领县二。乐宁，有成阳关、鸡头山。东随，有黄岘关、长平山庙。”（北京：中华书局，1974年，第2568页。）乐宁县治所当在原成阳治所附近。
③ 县废时间不详。同在宋安郡的东随县于589年改名礼山县，宋安郡同时废除，故推断乐宁县同年废除。",
