约翰·艾佛雷特·米莱（John Everett Millais，1829年6月8日－1896年8月13日），英国画家与插图画家，也是前拉斐尔派的创始人之一。

米莱生于英国南安普敦一个以泽西岛为根基的显要家庭。他惊人的画家天份使他在11岁时便进入英国皇家艺术学院就读，成为学院有史以来最年轻的学生。在那里，他认识了威廉·霍尔曼·亨特（William Holman Hunt）和但丁·加百利·罗塞蒂（Dante Gabriel Rossetti），他们三人在1848年一起成立了前拉斐尔派。

米莱的《基督在父母家中》（Christ in the House of his Parents, 1850）引起了极大的争议，因为他描绘出圣家庭一家人在满地木屑的杂乱木匠房里工作，后来的作品也引起相当争议。他的《一个胡格诺教徒》（A Huguenot, 1852）受到大众普遍欢迎，描绘一对情侣因为信仰的冲突而分手时的场景。他在后来许多作品中也描绘了类似的题材。

Sir John Everett Millais, 1st Baronet, PRA (/ˈmɪleɪ/; 8 June 1829 – 13 August 1896) was an English painter and illustrator who was one of the founders of the Pre-Raphaelite Brotherhood.

A child prodigy, at the age of eleven Millais became the youngest student to enter the Royal Academy Schools. The Pre-Raphaelite Brotherhood was founded at his family home in London, at 83 Gower Street (now number 7). Millais became the most famous exponent of the style, his painting Christ in the House of His Parents (1850) generating considerable controversy. By the mid-1850s Millais was moving away from the Pre-Raphaelite style and developing a new and powerful form of realism in his art. His later works were enormously successful, making Millais one of the wealthiest artists of his day. While early 20th-century critics, reading art through the lens of Modernism, viewed much of his later production as wanting, this perspective has changed in recent decades, as his later works have come to be seen in the context of wider changes and advanced tendencies in the broader late-nineteenth-century art world.
