周伯琦 （1298-1369）字伯温，号玉雪坡真逸，饶州人。以荫授南海县主簿，后转为翰林修撰。招识平江张士诚拜江浙行省左丞，留平江者十余年。 周伯琦工书，名显于当时，《元史》记载“帝以伯琦工书法，命篆宣文阁宝，乃题匾宣文阁及摹王羲之所书《兰亭序》、智永所书《千文》。刻石阁中。自是累转官皆宣文、崇文之间，而眷遇日隆矣。”同赵孟頫一样，也是皇帝“字而不名”的人物。
       博学工文章，而尤以篆、隶、其、草，擅名当时。篆师徐铉、张有行笔，结字殊有隶体，字颇肥，而玉润可爱。至正（一三四一至一三六七）间顺帝命篆“宣文阁宝”仍题扁。摹王羲之所书《兰亭序》、智永所书《千字文》，刻石阁中。二十二年（一三六二）临石鼓文册，现藏故宫博物院。卒年七十二。著有《六书正伪》、《说文字原》二书。

周伯琦，字伯温，饶州鄱阳人。父应极，至大间，仁宗为皇太子，召见，献《皇元颂》，为言于武宗，以为翰林待制。后为皇太子说书，日侍英邸。仁宗即位，迁集贤待制，终池州路同知总管府事。伯琦自幼从宦，游京师，入国学，为上舍生，积分及高等。去，以廕授将仕郎、南海县主簿，三转为翰林修撰。至正元年，改奎章阁为宣文阁、艺文监为崇文监，伯琦为宣文阁授经郎，教戚里大臣子弟，每进讲，辄称旨，且日被顾问。帝以伯琦工书法，命篆“宣文阁宝”，仍题扁宣文阁；及摹王羲之所书《兰亭序》、智永所书《千字文》，刻石阁中。自是累转官，皆宣文、崇文之间，而眷遇益隆矣。帝尝呼其字伯温而不名。会御史奏风宪宜用近臣，特命佥广东廉访司事。八年，召入为翰林待制，预修后妃、功臣列传，累升直学士。
       十二年，有旨令南士皆得居省台。除伯琦兵部侍郎，遂与贡师泰同擢监察御史。两人皆南士之望，一时荣之。时御史大夫也先帖木儿以大军南讨，而失律丧师，陕西行台监察御史刘希曾等十人共劾奏之。伯琦乃劾希曾等越分干誉，希曾等皆坐左迁，补郡判官，由是不为公论所与。
       十三年，迁崇文太监，兼经筵官，代祀天妃。丁内艰。十四年，起复为江东肃政廉访使。长枪锁南班陷宁国，伯琦与僚佐仓皇出见之，寻遁走至杭州。除兵部尚书，未行，改浙西肃政廉访使。江南行台监察御史余观纠言伯琦失陷宁国，宜正其罪。十七年，江浙行省丞相达识帖睦尔承制假伯琦参知政事，招谕平江张士诚。士诚既降，江南行台监察御史亦辩释伯琦罪，除同知太常礼仪院事，士诚留之，未行，拜资政大夫、江浙行省左丞。于是留平江者十余年。士诚既灭，伯琦乃得归鄱阳，寻卒。
伯琦仪观温雅，粹然如玉，虽遭时多艰，而善于自保。博学工文章，而尤以篆、隶、真、草擅名当时。尝著《六书正伪》、《说文字原》二书，又有诗文稿若干卷。
