Katharina Sibylla Schücking (née Busch; 26 January 1791, Ahlen – 2 November 1831, Ludmillenhof, Sögel, near Meppen) was a German poet from Westphalia.
She spent 1807 to 1809 in Münster, where her literary talent was recognised and encouraged by Anton Matthias Sprickmann and where she also joined the circle of Adelheid Amalie Gallitzin.
This led to her being scorned and ridiculed but did not do permanent damage to her reputation as a poet – in 1813 she first met Annette von Droste-Hülshoff, becoming a close friend and thinking of her as her "poetic idol".
The couple had six children: Christoph Bernhard Levin Matthias (1814–1883); Peter August Gerhard (1816–1817); Anton Matthias Franz Alfred (1818–1898); Ida Josephina Theophania Desideria (1821–1883); Modesta Paulina Nicolaia Roswitha (1825–1896); and Prosper Ludwig (1828–1887).
In 1815, the Schücking family moved to Sögel, leaving Katharina socially and geographically isolated and bringing her writing to a standstill.
