Ludwig Ross (22 July 1806, Bornhöved – 6 August 1859, Halle an der Saale) was a German classical archaeologist. His family came from northern Scotland, and his father, Colin Ross, married Juliane Auguste Remin and managed the Gut Altekoppel in Bornhöved; their many children included Ludwig's younger brother the painter Karl Ross.
Ludwig studied classical philology at the Christian-Albrechts-Universität in Kiel. He graduated from there with a PhD thesis on Aristophanes before going on research trips to Greece, western Asia Minor and Cyprus.
