Thomas Chrowder Chamberlin (September 25, 1843 - November 15, 1928) was an influential American geologist and educator. In 1893 he founded the Journal of Geology, of which he was editor for many years.
In 1905, Chamberlin and Forest Ray Moulton developed a theory of the formation of the solar system that challenged the Laplacian nebular hypothesis. Their theory, the Chamberlin-Moulton planetesimal hypothesis, received favourable support for almost a third of a century, but passed out of favour by the late 1930s. It ultimately was discarded in the 1940s by the realisation it was incompatible with the angular momentum of Jupiter.
