Wilhelm Georg Alexander von Kügelgen (20 November 1802, in St.Petersburg – 25 May 1867, in Ballenstedt) was a German portrait and history painter, writer, and chamberlain at the Court of Anhalt-Bernburg.
When he was eighteen, his father was murdered during a robbery, creating an emotional crisis that challenged his religious beliefs.
In 1833, he became the Court Painter at the Anhalt-Bernburg summer residence in Ballenstedt and remained there the rest of his life.
From 1853 to 1863, he served as personal chamberlain to Duke Alexander Karl, who was suffering from a severe mental illness.
Since 1993, the Kunstkreis Sachsen-Anhalt in Bernburg has awarded an annual "Wilhelm von Kügelgen Scholarship" to art students.
