Clifford Howard Stockwell (September 26, 1897 – April 26, 1987) was a Canadian geologist, who published many scientific papers, reports and memoirs in the fields of Mineralogy, Structural Geology, Petrology, and Stratigraphy.
He completed his earliest publication, "Galena Hill, Mayo District, Yukon", in 1925 as a graduate student.
In 1927, Stockwell's paper on "The X-ray Study of the Garnet Group", earned him recognition, as it was an important step in the understanding of the crystal structure of these minerals.
Some of his other noteworthy papers include; "The Chromite Deposits of the Eastern Townships, Quebec," "The Gold Deposits of Herb Lake Area", and "The Rice Lake-Gold Lake Area", in Manitoba.
This work delineated the basic features and problems of the geology of this large part of the Precambrian Shield, and laid the foundation for the many studies that followed.
