Adalbert Merx (2 November 1838 – 6 August 1909) was a German Protestant theologian and orientalist.
He studied at the University of Jena, where he became an associate professor in 1869. Subsequently, he was a full professor of philosophy at the University of Tübingen, and in 1873 a professor of theology at the University of Giessen. From 1875 till his death he was a professor of theology of the University of Heidelberg. In the course of his researches he made several journeys in the East.
Merx devoted much of his later research to the elucidation of the Sinaitic Palimpsest discovered in 1892 by Mrs. Agnes Smith Lewis, the results (Die Evangelien des Markus und Lukas nach der Syrischen im Sinaikloster gefundenen Palimpsesthandschrift) being embodied in Die vier kanonischen Evangelien nach dem ältesten bekannten Texte (4 volumes, 1897–1905). His last work was an edition of the books of Moses and Joshua.
