Lucian Reich was a German painter and writer.

Lucian Reich's father was the schoolteacher, sculptor and painter Lucian Reich (the elder), his grandfather was Mathias Reich and his brother-in-law the lithographer and photographer Johann Nepomuk Heinemann, with whom he worked closely. His brother Franz Xaver Reich was a sculptor. Lucian Reich received his first drawing lessons at his father's painting and drawing school. He took lessons at the Städelsches Institut in Frankfurt under the painter Philipp Veit, and later went to Munich. From 1855 to 1899 he worked as a drawing teacher at the Lyceum in Rastatt. One of his students there was Heinrich Hansjakob.

In addition to oil paintings and lithographs, he also painted pictures for churches, e.g. in 1867 for St. Birgitta in Iffezheim, where he created wall paintings of Saints Bernhard, Wendelin, Sebastian and Johann von Nepomuk. In 1877, a contract for two further paintings followed, of which, however, only one still exists. He painted the two side altar paintings in the parish church in Hüfingen, and the ceiling painting of Saint Ottilie and a wall painting in the choir showing Saint Sebastian in the Ottilienkapelle in Bräunlingen. In 1865, he also created an altarpiece for St. Leon and a depiction of the Assumption of Mary for the Bernhardus Church in Rastatt. The three planned choir paintings from the life of Saint Gallus for the new church in Altschweier (1866) and cardboard drawings for two windows in Rippoldsau (1859) were not realized. He also worked as a costume painter.

As a religious writer, he wrote, among other things: Bruder Martin (1853) and Hieronymus.

He was in contact with, among others, his uncle Johann Nepomuk Schelble, Moritz von Schwind, Joseph Bader, Lukas Engesser and Victor Scheffel.

A great-great-great-niece of his is the musician, painter and writer Hortense von Gelmini.
