George Arthur Williams (August 17, 1864 – July 7, 1946) was a 20th-century politician who served as the 18th lieutenant governor of Nebraska from 1925 to 1931.

In 1888, he married Mabel L. Grubb, with whom he would eventually have eight children, and moved to Fairmont, Nebraska where his wife's family owned a farm.

In 1914, he and family moved back to the Grubb farm in Fairmont and became involved in community affairs, managing an American Red Cross fund drive and serving on the Fillmore County Council of Defense during World War I.

As a legislator, he focused on road and farming issues and supported ratification of the Eighteenth Amendment to the United States Constitution.
