伊顿公学（Eton College），全名为温莎宫畔伊顿圣母英皇书院（The King's College of Our Lady of Eton beside Windsor），是英国著名的男子公学，位于英格兰温莎，泰晤士河边。

1440年，亨利六世创立了伊顿公学，最早为七十名贫穷学生提供免费教育，作为进入剑桥大学英皇学院的预备学校。早期伊顿公学是一所平民学校，但到17世纪以后，学校逐渐贵族化，一直以来英国的皇室成员都把男孩子送到伊顿公学，伊顿还培养了十九名首相。著名的校友包括了雪莱、乔治·奥威尔、亨利·菲尔丁、伊恩·弗莱明、亨利·萨尔（后来成为伊顿校长）、凯恩斯、威灵顿公爵、和威廉王子等人。
