George Wingfield (August 16, 1876 – December 25, 1959) was a Nevada cattleman and gambler who became a financier, investor and one of the state's most powerful economic and political figures during the period from 1909 to 1932. With future senator George S. Nixon as his mentor after he settled in Winnemucca in 1899, and fellow gambler John Hennessy as his partner in the mining boomtown of Tonopah after 1901, Wingfield rose from faro-dealer to become richest man in Nevada in less than five years.
