Dennis Bell (December 28, 1866 – September 25, 1953) was a Buffalo Soldier in the United States Army and a recipient of America's highest military decoration—the Medal of Honor—for his actions in the Spanish–American War.

Bell and three of his fellow Buffalo Soldiers were the last black servicemen to be presented the Medal of Honor for more than half a century.

On that day, American forces aboard the Florida near Trinidad, Cuba, dispatched a landing party to provide reconnaissance on Spanish outposts in the area.

The fifth attempt, manned by Bell and three other privates of the 10th Cavalry (Fitz Lee, William H. Thompkins, and George H. Wanton) under the command of Lieutenant Ahern, launched at night and successfully found and rescued the surviving members of the landing party.

Private Bell's official Medal of Honor citation reads: Voluntarily went ashore in the face of the enemy and aided in the rescue of his wounded comrades; this after several previous attempts at rescue had been frustrated.Bell died at the Mount Alto Veterans Hospital in Washington, D.C., on September 25, 1953, and was buried at Arlington National Cemetery, in Arlington, Virginia.
