Anatoly Nikolayevich Ryabinin ( Russian Анатолий Николаевич Рябинин * May 30 jul. / 11. June  1874 greg. In Murom ; † 12. February 1942 in Leningrad ) was a Russian geologist and paleontologist.

Ryabinin graduated from the Mining Institute in Saint Petersburg in 1897. Alexander Petrovich Karpinsky was one of his teachers . He was arrested twice for revolutionary activities and was then exiled to Tbilisi and the Vyatka Governorate (1897 to 1905) and was only able to return to Saint Petersburg in 1905. From 1901 he was in the Geological Committee, the later All-Union Committee for Geology (Geological Committee), whose Vice Director he was from 1918 to 1921 and its director from 1921 to 1923. He was also 1919 to 1922 professor at the Mining Academy in Moscow and then at the Mining Institute in Leningrad. In 1935 he received the Russian doctorate (habilitation). In 1916 he was one of the founders of the Russian Paleontological Society and in 1941 its chairman. He died of starvation during the siege of Leningrad.

He was on field studies in the Caucasus, Crimea, Central Asia, Kazakhstan, Perm and Kirov. His paleontological work on the Tertiary in the Caucasus region led to the discovery of new oil fields. He was one of the first to point out the presence of potash salt in the Urals. As a paleontologist he dealt with vertebrate palaeontology (mammals, reptiles, amphibians, especially dinosaurs).

A genus of pterosaurs was first described by him ( Batrachognathus RJABININ 1948).
