Arden Hayes (born January 30, 2008) is from Southern California in the United States. He became known at age 5 for his knowledge of the U.S. presidents, reciting Lincoln's Gettysburg Address, and being able to identify the countries of the world and name the capitals of each.

His interest in American presidents was sparked by Arden’s learning that he shares a birthday with former United States President Franklin Delano Roosevelt.

On May 4, 2013, Arden was featured in an article and video in the Los Angeles Times. This spurred many additional newspaper articles and blogs and Arden appeared on Jimmy Kimmel Live! on July 2, 2013, to demonstrate his knowledge regarding U.S. presidents. On November 5, 2013, Arden again appeared on Jimmy Kimmel Live!, and displayed his knowledge of the nations of the world and their capitals and rejected a free Sony Xperia Tablet Z because he preferred the Apple iPad and would rather wait until Christmas to receive it. He appeared on Jimmy Kimmel Live! for the third time on April 2, 2014, and showed his interest and knowledge about chemical elements in the periodic table. He appeared on the show again on November 23, 2015, when he won a shut-out victory against the cast of Star Wars: The Force Awakens in a Star Wars trivia contest.
