Robert Lee Williams (December 20, 1868 – April 10, 1948) was an American lawyer, judge, and the third governor of Oklahoma. Williams played a role in the drafting of the Oklahoma Constitution and served as the first Oklahoma Supreme Court chief justice. He also served as a United States circuit judge of the United States Court of Appeals for the Tenth Circuit and as a United States district judge of the United States District Court for the Eastern District of Oklahoma. As third Governor, Williams oversaw the state's response to the recent United States Supreme Court's ruling against Jim Crow laws and its involvement in the First World War (1914/1917-1918). He instituted the Oklahoma State Board of Affairs (later reorganized into the current Oklahoma Department of Central Services) which provided central purchasing services to various state departments, agencies, boards and bureaus. Due to his direct administrative role and concentration of power, Governor Williams counteracted the previous loss of executive power and disagreements with the Oklahoma Legislature under previous second Governor Lee Cruce (1863-1933, served 1911-1915).
