Lemuel Cook (September 10, 1759 – May 20, 1866) was one of the last verifiable surviving veterans of the American Revolutionary War.

He was assigned to the 2nd Continental Light Dragoons, and by his death he was the last surviving member.

He died May 20, 1866,[2] at the age of 106, having lived to see the start and the end of the American Civil War.

At the time of his death, only three other revolutionary veterans (Samuel Downing, Daniel F. Bakeman and John Gray) were still alive.

He was one of seven American Revolutionary War veterans who, having survived into the age of photography, were featured in the 1864 book The Last Men of the Revolution, which gives many details of his life.
