Frantz Johannes Hansen (4 September 1810 in Copenhagen – 14 March 1852) was a Danish author and was also an amateur musician.
In 1834, Hansen received a law degree, which later earned him a modest living, first working in the Archives Office.
However, in his leisure time he continued to pursue his literary ambitions: in 1839 he issued a volume of Romantic poems, which contained one of his best-known pieces, "Korsaren og hans Brud" (The Corsair and his Bride).
Hansen attempted dramatic writing, some of which appeared at the Royal Danish Theatre, but did not have a successful debut.
After Hansen's death, his collection Lyriske Digte (Lyrical Poems, 1852) was published with a preface that gives a brief biography of the writer.
