古斯塔夫·克林姆（德语：Gustav Klimt，1862年7月14日－1918年2月6日，又译古斯塔夫·克里姆特）生于维也纳，是一位奥地利知名象征主义画家。他创办了维也纳分离派，也是所谓维也纳文化圈代表人物。

古斯塔夫·克林姆画作特色在于特殊的象征式装饰花纹，并在画作中大量使用性爱主题。喜欢他画作的人称赞有其「沉闷美感」与大胆象征寓意，但是却也招致不少保守派画家的负面评价。

克林姆画作另一特色为画中主角大部分都是女人，主题则为「爱」、「性」、「生」与「死」的轮回宿命。

克林姆1918年因患上西班牙型流行性感冒而身故。

Gustav Klimt (July 14, 1862 – February 6, 1918) was an Austrian symbolist painter and one of the most prominent members of the Vienna Secession movement. Klimt is noted for his paintings, murals, sketches, and other objets d'art. Klimt's primary subject was the female body, and his works are marked by a frank eroticism. In addition to his figurative works, which include allegories and portraits, he painted landscapes. Among the artists of the Vienna Secession, Klimt was the most influenced by Japanese art and its methods.
