William G. Blakely (August 29, 1829 – April 19, 1920) was an American miner, lawyer, and a Methodist minister.

In 1861, he left California and moved his family to Carson City in the adjacent Nevada Territory where he began the practice of law.

Blakely then relocated to Austin where he constructed a Methodist Episcopal Church and served as its pastor.

He was the attorney in Kingman for the Atchison, Topeka, and Santa Fe Railroad, and also represented many other large mines and businesses in the area.

[4] He then became a superior court judge, and representative in the upper house of the 24th Arizona Territorial Legislature of 1907.

[6] Blakely was an honorary member of the Woman's Christian Temperance Union and publicly spoke in support of prohibition based on his experiences with alcohol consumption in mining communities.

[14] Blakely's house, built in 1887 and located at 503 Spring Street in Kingman, has been listed on the National Register of Historic Places since 1986.
