So named in 1901 by Schrader (1904, p. 111) and W. J. Peters, U.S. Geological Survey (USGS), "because the Thetis Coal Mine is near its mouth." The Thetis Coal Mine was named about 1889 for the U.S.S. Thetis. The Eskimo name for this stream is "Igikalik" which is said, by U.S. Coast and Geodetic Survey (USC&GS), to refer to the "black cormorant."
