William Sutphen Graham (fl. c. 1890 - 1900) was the county surveyor of Placer County, California at the end of the 19th century. Born in Illinois, he is recorded as having resided in Auburn, the seat of Placer County, from 1886, being listed in census records and city directories as either a surveyor or civil engineer. He appears to have stopped holding the position of County Surveyor soon after the turn of the century, with no information available about his subsequent life and works.
