亨利一世（英语：Henry I；约1068年–1135年12月1日），亦被称为儒雅者亨利（英语：Henry Beauclerc），是1100年至1135年在位的英格兰国王。亨利是征服者纪尧姆第四子，曾学习拉丁语并接受博雅教育。1087年，威廉死亡，亨利的长兄短袜罗贝尔和三兄红毛威廉分别继承了诺曼底和英格兰，但亨利却没有分到土地。亨利从罗贝尔那里购买了位于诺曼底西部的科唐坦郡，但在1091年，威廉和罗贝尔废黜了他对科唐坦郡的所有权。在与威廉结盟对抗罗贝尔的基础上，亨利逐渐恢复了自己的权势。在1100年，纪尧姆死于一场狩猎事故，亨利夺取了英格兰王位，并在加冕礼上承诺要更改威廉的许多不合民意的政策。亨利迎娶了苏格兰的玛蒂尔达，但还是和数以百计的情妇生有大量非婚生子女。

Henry I (c. 1068 – 1 December 1135), also known as Henry Beauclerc, was King of England from 1100 to his death. Henry was the fourth son of William the Conqueror and was educated in Latin and the liberal arts. On William's death in 1087, Henry's elder brothers Robert Curthose and William Rufus inherited Normandy and England, respectively, but Henry was left landless. Henry purchased the County of Cotentin in western Normandy from Robert, but William and Robert deposed him in 1091. Henry gradually rebuilt his power base in the Cotentin and allied himself with William against Robert. Henry was present when William died in a hunting accident in 1100, and he seized the English throne, promising at his coronation to correct many of William's less popular policies. Henry married Matilda of Scotland but continued to have a large number of mistresses, by whom he had many illegitimate children.
