What president is on a five dollar note?

A portrait of Abraham Lincoln, the 16th President of the United States, is on the front of the US $5 bill. If you look below the portrait, there's a small caption with his name. All U.S. bills have similar captions that identify both the person on the bill's front and the scene on the bill's back.

The Lincoln Memorial is on the back.

Lincoln is also on the 1 cent coin, and the Lincoln Memorial was on the back of the cent from 1959 to 2008.
