克里斯蒂安·约翰·海因里希·海涅（德语：Christian Johann Heinrich Heine，1797年12月13日－1856年2月17日），出生时用名哈利·海涅（Harry Heine），19世纪最重要的德国诗人和新闻工作者之一。海涅既是浪漫主义诗人，也是浪漫主义的超越者。他使日常语言诗意化，将报刊上的文艺专栏和游记提升为一种艺术形式，赋予了德语一种罕为人知的风格上的轻松与优雅。作为批评家、热心于政治的新闻工作者、随笔作家、讽刺性杂文作家、论战者，他既受喜爱，又遭惧怕。他是作品被翻译得最多的德国诗人中的一员。海涅最广为人知的一首诗可能是由门德尔松为之作曲的通过音乐传播的《乘着歌声的翅膀》。

Christian Johann Heinrich Heine (13 December 1797 – 17 February 1856) was a German poet, journalist, essayist, and literary critic. He is best known outside Germany for his early lyric poetry, which was set to music in the form of Lieder (art songs) by composers such as Robert Schumann and Franz Schubert. Heine's later verse and prose are distinguished by their satirical wit and irony. He is considered part of the Young Germany movement. His radical political views led to many of his works being banned by German authorities. Heine spent the last 25 years of his life as an expatriate in Paris.
