Looking up the U.S. presidents in alphabetical order is one of those things that sounds simple until you actually try to do it from memory. Most people learn them in chronological order - Washington, Adams, Jefferson - but sorting them by last name is a different exercise entirely. Below you'll find the full list of all 45 individuals who have served as president, sorted alphabetically by last name. You can also browse the official White House presidential biographies for more detail on each.
Quick note on the count: there have been 46 presidencies but only 45 different people, because Grover Cleveland served two non-consecutive terms (he was both the 22nd and 24th president). And with Donald Trump serving as both the 45th and 47th president, the numbering gets a little tricky. But the alphabetical list below covers every person who has held the office.
Why Sort Presidents Alphabetically?
Chronological order is great for understanding history, but alphabetical order is more practical when you need to look someone up quickly. If you're writing a research paper and need to check whether someone served before or after the Civil War, scanning an alphabetical list makes it easy to find the name first and then check the dates. Teachers and quiz makers use alphabetized president lists when they don't want the answer order to give away clues about time periods.
It's also a good study trick. Going through the presidents alphabetically forces your brain to recall them in a different order than you learned them, which actually strengthens your memory of each one. You start noticing patterns too - like how many presidents had the first name James (six of them, more than any other first name).
Patterns in Presidential Names
Once you alphabetize the list, some interesting things jump out. The letters A, B, and J are packed with presidents. Adams, Arthur, and two different entries for Adams alone cover the A section. The B's include Buchanan, both Bushes, and Biden. And the J's have Jackson, Jefferson, both Johnsons, and more.
On the flip side, several letters have zero presidents. No president's last name has started with D, I, Q, S, U, X, Y, or Z. That's a lot of empty letters. The most common presidential last name pattern is actually "H" names - Harrison (two of them, grandfather and grandson), Hayes, Harding, Hoover - five presidents starting with H.
First names tell a story too. James has been the most popular presidential first name with six holders: Madison, Monroe, Polk, Buchanan, Garfield, and Carter (whose full name is James Earl Carter Jr.). John comes in second with five: Adams, Tyler, the other Adams, Kennedy, and arguably Calvin Coolidge whose birth name was John Calvin Coolidge Jr.
