Lodewijk De Koninck (Hoogstraten, 30 October 1838 - Retie, 22 March 1924) was a Flemish writer.
He studied at the school for teachers Lier and became a teacher in Antwerp. Later he became an inspector of the Catholic primary schools and a teacher at the school for teachers in Mechelen.
As a writer he wrote poems which reflected his strict catholic belief. He is best known for the epic Het menschdom verlost (first edition 1872) (E: Humanity saved), written in Alexandrine verse. He also wrote the libretto of the oratorio Fransciscus of Edgar Tinel.
At the frontwall of his house in the Sint-Martinusstraat (nr. 8) in Retie, there was, in earlier days, a stone with the engraving Hier leefde en stierf dichter Lodewijk De Koninck 1924 (e: Here lived and died the writer Lodewijk De Koninck 1924).
