George Cochrane Hazelton (January 3, 1832 – September 4, 1922) was an American attorney and politician.

He was elected to the Wisconsin State Senate in 1867 and was reelected in 1869 and served as president pro tempore.

[3] He was unsuccessful candidate for renomination in 1882 and settled in Washington, D.C., where he practiced law and served as the attorney general for the District of Columbia during the Harrison administration.

He argued against the immigration of "unworthy" races, and said of the Chinese "I know that if the segment of her population now upon the Pacific shores is the standard and measure of her home civilization, it is of the lowest order.”[4] Hazelton was son of William and Mercy Jane Hazelton.

His older brother, Gerry Whiting Hazelton, was also a member of Congress, and a prominent lawyer in Wisconsin.
