Paul Fallot (25 June 1889 in Strasbourg – 21 October 1960 in Paris) was a French geologist and paleontologist.
In 1909 he moved to Grenoble to work at the laboratory of geologist and paleontologist Wilfred Kilian on ammonites of the Balearic Islands.
In 1910-1911 he broadens his knowledge of general geology and stratigraphy at the Sorbonne led with Emile Haug.
After the war, Fallot was employed by his former teacher Kilian in Grenoble and continued his work in Mallorca.
His appointment in 1937 as professor of Geology of the Mediterranean at the Collège de France, seemed the opportunity to scale up his work on the tectonics of the entire area with a team of specialists, but the outbreak of World War II hindered this.
