Dimitri Kaljo (born 12 October 1928) is an Estonian geologist and palaeontologist whose work has focused on the Ordovician and Silurian systems, including rugose corals and graptolites, Baltic basin evolution, and stratigraphic methods such as ecostratigraphy and isotope stratigraphy. He has been a member of the Estonian Academy of Sciences since 1983. Internationally, he served as chairman of the International Union of Geological Sciences / International Commission on Stratigraphy Subcommission on Silurian Stratigraphy (commonly given as 1984–1992) and was elected an Honorary Fellow of the Geological Society of London (1987).

Service and leadership A biographical dedication in the Academy’s geology proceedings credits Kaljo with leadership roles in national commissions (including stratigraphy and mineral resources) and international bodies, including the Subcommission on Silurian Stratigraphy and vice-presidential roles in international palaeontological organisations.
