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.

[4] He then married a divorced woman, Maud Azil Murdoch Hamlin of San Francisco, and they had a son, George Wingfield Jr.

By age 20, Wingfield had become a cattle drover, and drove herds from Oregon and California eastward to Winnemucca in Humboldt County (in the state's northwestern corner).

In Winnemucca, Wingfield met former railroad man turned banker and future United States Senator George S. Nixon, sixteen years his senior, and who became his mentor.

In 1899, Wingfield decided to leave the cattle business and opened a saloon in Golconda, also in Humboldt County, but sold it by 1901.

By 1904, having grub-staked many miners after a gold strike the previous year about 27 miles away in Goldfield, Esmeralda County, Nevada, Wingfield moved to Goldfield, and also bought a saloon, which his millionaire mentor Nixon advised him to sell and concentrate on respectable investments, so over the next years they bought more real estate and all but one of the local mines.

By his 30th birthday in 1906 (also the year his father died in San Francisco), Wingfield had made a fortune in Nevada, based on mine ownership in Tonopah and Goldfield.

In the 1920s Wingfield worked with legislators to make Nevada a quickie divorce location, which helped his Reno hotel businesses.
