Gabriel Edward Parker[1] (September 29, 1878 – May 8, 1953) was an American public servant.

Born in the Indian Territory, he attended the 1906 Oklahoma Constitutional Convention and was heavily involved in the design of the state's seal.

Parker was later Register of the Treasury (1913-1914) and superintendent of the Five Civilized Tribes (1915-1921).

His appointment was reported as marking the first time a Native American held the post.

[3] Parker died from a heart attack at his home in Oklahoma City on May 8, 1953, a few hours after hearing of his son's death from a heart attack in England on the same day.
