William Wright (1829–1898), better known by the pen name Dan DeQuille or Dan De Quille, was an American author, journalist, and humorist. He was best known for his written accounts of the people, events, and silver mining operations on the Comstock Lode at Virginia City, Nevada, including his non-fiction book History of the Big Bonanza (American Publishing Company, 1876).

DeQuille was on the staff of the (Virginia City) Territorial Enterprise for over thirty years, and his writings were also printed in other publications throughout the country and abroad. Highly regarded for his knowledge of silver mining techniques and his ability to explain them in simple terms, he was also appreciated for his humor, similar in style to that of his associate and friend Mark Twain, and of a type very popular in the United States at that time, now referred to as the Sagebrush School literary genre.
