约翰·拉斯金（John Ruskin，1819年2月8日－1900年1月20日）是英国维多利亚时代主要的艺术评论家之一，他还是一名艺术赞助家、制图师、水粉画家、和杰出的社会思想家及慈善家。他写作的题材涵盖从地质到建筑、从神话到鸟类学、从文学到教育、从园艺学到政治经济学包罗万象。他的写作风格和体裁同样多变。拉斯金写过从随笔到专着、从诗歌到演讲、从旅行指南到说明书、书信甚至到童话。在他所有的作品中，他无一不在强调自然、艺术和社会之间的联系。1843年，他因《现代画家》（Modern Painters）一书而成名，书中，他高度赞扬约瑟夫·玛罗德·威廉·透纳的绘画创作。这以及其后的写作总计39卷，使他成为维多利亚时代艺术趣味的代言人。他是前拉斐尔派的一员，本身亦为天才而多产的艺术家。

John Ruskin (8 February 1819 – 20 January 1900) was the leading English art critic of the Victorian era, also an art patron, draughtsman, watercolourist, a prominent social thinker and philanthropist. He wrote on subjects as varied as geology, architecture, myth, ornithology, literature, education, botany and political economy. His writing styles and literary forms were equally varied. Ruskin penned essays and treatises, poetry and lectures, travel guides and manuals, letters and even a fairy tale. The elaborate style that characterised his earliest writing on art was later superseded by a preference for plainer language designed to communicate his ideas more effectively. In all of his writing, he emphasised the connections between nature, art and society. He also made detailed sketches and paintings of rocks, plants, birds, landscapes, and architectural structures and ornamentation.
