约刘玄更始元年（公元23年）以泽亭县恢复旧名。⑴治所在今河北沧州市西南。⑵东汉属河间郡、河间国。⑶三国魏属河间郡。⑷西晋属河间国。⑸

⑴按：王莽败后，全国复汉旧郡、县名，但何时复名，未详。据《后汉书》卷11《刘玄刘盆子传》：更始即帝位，建元曰更始元年（23年），“是时海内豪桀翕然响应，皆杀其牧守，自称将军，用汉年号，以待诏命，旬月之间，徧于天下”。（2册，469页）据此，姑作刘玄更始元年（23年）复旧名。
⑶《续汉书?郡国志》，《后汉书》，第12册，第3436页。
⑷吴增仅撰、杨守敬补正：《三国郡县表附考证》，《二十五史补编》本，第30页。
⑸《晋书》卷14《地理上》，第2册，第424页。    ]]>  </source-note>  <source-uri>      </source-uri></placename>
