Adam Gottlob Oehlenschläger (14 November 1779 – 20 January 1850) was a Danish poet and playwright. He introduced romanticism into Danish literature. He wrote the lyrics to the song Der er et yndigt land, which is one of the national anthem of Denmark.

He was born in Vesterbro, then a suburb of Copenhagen. His father, Joachim Conrad Oehlenschläger (1748–1827) was at that time organist of Frederiksberg Church and later, keeper of the royal palace of Frederiksberg. The poet’s mother Martha Marie Hansen (1745–1800) suffered from depression, which afterwards deepened into melancholy madness

Oehlenschläger and his sister Sophie Ørsted (1782-1818) were taught only to read and write, until their twelfth year. At the age of nine, Oehlenschläger began to write fluent verses. Three years later, he attracted the notice of the poet Edvard Storm (1749–1794) and as a result Öhlenschläger received an introduction into Scandinavian mythology.
