Carl Gustaf Verner von Heidenstam (6 July 1859 – 20 May 1940) was a Swedish poet and novelist, a laureate of the Nobel Prize in Literature in 1916. He was a member of the Swedish Academy from 1912. His poems and prose work are filled with a great joy of life, sometimes imbued with a love of Swedish history and scenery, particularly its physical aspects.

He was born in Olshammar, Örebro County to a noble family. He studied paintings in the Academy of Stockholm, but soon left because of ill health. He then traveled extensively in Europe, Africa and the orient. He was at once greeted as a poet of promise on the publication of his first collection of poems, Vallfart och vandringsår (Pilgrimage: the Wander Years, 1888). It is a collection of poems inspired by his experiences in the orient and marks an abandonment of naturalism that was dominant then in Swedish literature.
His love for beauty is showed also by the long narrative poem Hans Alienus (1892). Dikter ("Poems", 1895) and Karolinerna (The Charles Men, 2 vols., 1897–1898), a series of historical portraits of King Charles XII of Sweden and his cavaliers, shows a strong nationalistic passion. English translations of short stories from Karolinerna can be found in the American-Scandinavian Review (New York), May 1914, November 1915, and July 1916. The two volumes of Folkunga Trädet (The Tree of the Folkungs, 1905–07) are the inspired, epic story of a clan of Swede chieftains in the Middle Ages.
In 1910 a controversy was waged in Swedish newspapers between a number of Swedish literary men on the topic of the proletarian “degradation” of literature, the protagonists of the two opposing camps being August Strindberg and Heidenstam. Professors Lidforss and Böök also took part. Heidenstam's chief contribution was the pamphlet, directed chiefly against Strindberg, “Proletärfilosofiens upplösning och fall” (“The Decline and Fall of the Proletarian Philosophy”).
Heidenstam's poetical collection Nya Dikter, published in 1915, deals with philosophical themes, mainly concerning the elevation of man to a better humanity from solitude.
He died at his home Övralid in 1940.

Carl Gustaf Verner von Heidenstam was born at Ölshammar, his grandmother's estate on the shores of Lake Vättern, into an aristocratic and wealthy family. In his childhood Heidenstam got used to being center of attention and self-assertion became part of his perrsonality. When he dressed as a king, his grandmother told household servants to play his underlings. At school Heidenstam was lazy, and his educations was superficial – he had troubles in grammatical correctness, he was mostly alone or spent time with female relatives or friends who let him dominate the scene.
- At the age of sixteen his parents sent him on a journey to Middle East, Greece, and Italy with his cousin Ernst von Heidenstam. On the second journey his companion was Carlo Landberg, a linguistic. The travels in the Mediterranean influenced Heidenstam's first poems, which formed a colorful contrast to the prevailing gloomy mood in literature.
Colonel Gustaf von Heidenstam had tried in vain to change his son's aimless life style, and eventually sent him to Paris to study art under Jean Léon Gérôme at the École des Beaux Arts. There Heidenstam boasted with his great plans, emphasized his aristocratic background, but actually did not show any ambitions to become an artists. After returning to Sweden in 1880, he married against his father's wishes Emilia Uggla, a Swiss woman. During the following years Heidenstam lived with his wife in Italy, France, and Norway.
Heidenstam sent his early poems to the Finnish writer Zachris Topelius, who encouraged him to continue.

In 1886 the Heidenstams leased a medieval castle in northern Switzerland. The regular visitors there included the writer August Strindberg, with whom Heidenstam later disputed. Strindberg was provoked Heidenstam's manifesto Renässans (1889), in which he rejected social realism in favour of imagination.

In 1887 Heidenstam returned to Sweden and settled on the family estate. His relationship with his father had improved, but facing an incurable illness Gustaf von Heidenstam committed suicide.

He never witnessed the appearance of his son's first collection of poems, Pilgrimage and Wander Years, (1888), which was an immediate success, but nowadays its Arabian Nights vision of the Middle Eastas a place of exotic pleasures is considered outdated
