Walter James Robertson (October 2, 1910 - May 9, 1978) was an American publisher and cartographer. Born in Colorado, Robertson lived most of this life in Stockton, California. Beginning in the 1950s (or possibly earlier), Robertson began publishing materials dealing with mining, including a pamphlet titled 'Gold Panning for Profit'. He also published a series of placer mining maps of several western states, including Oregon, Arizona, and Northern and Southern California.
