Wilhelm Waiblinger (; 21 November 1804 – 17 or 30 January 1830) was a German
romantic poet, mostly remembered today in connection with
Friedrich Hölderlin. After he had attended
Gymnasium Illustre in
Stuttgart, he was a student at the seminary of
Tübingen in the 1820s, when Hölderlin, already mentally ill, lived there as a recluse in a carpenter's house. Waiblinger, who used to visit the older poet and take him out for walks, left an account of Hölderlin's life then,
Hölderlins Leben, Dichtung und Wahnsinn ("Hölderlin's life, poetry and madness"). In the late 1820s, Waiblinger left Tübingen for
Italy, dying at the age of 25 in Rome, where he is buried in the
Protestant Cemetery.
