John Randolph Tucker (August 13, 1854 – December 18, 1926) was an American judge and Democratic politician who served as a member of the Virginia Senate. He was born in Philadelphia to Dr. David Hunter Tucker and the former Elizabeth Dallas. His father, son of Henry St. George Tucker, Sr., was then serving as Dean of the Medical College of Virginia. He was sometimes referred to as "J. Randolph Tucker, Jr.," to distinguish him from his uncle, a U.S. congressman.
