How it works

These long last names are the 600 most common US surnames of 12 letters or more in the 2020 Census file. Hollingsworth leads, with 22,814 people; each card gives the letter count, the rank and the count.

Read the full guide

Sort long last names by length

The dropdown, Letters, keeps the 437 names of 12 letters, the 120 of 13, the 36 of 14 or the 7 of 15. Under More filters, Rank band keeps the 26 names in the top 10,000, such as Higginbotham and Wojciechowski, or the 278 beyond rank 50,000.

Why double names are left out

The census file drops hyphens and spaces, so a double name is stored as one word: Garcia Hernandez becomes a 15-letter entry. Entries that are two common surnames run together are passed over. 98 cards add the origin a dictionary gives: Satterthwaite is Old Norse for a pasture and a clearing.

Tips
  • Last names that are long and start with S are the largest group: 110 of the 600.
  • A card with no line after the count has no plain dictionary entry; nothing was guessed.

Questions and answers

What is the longest last name in the US?

In the Census Bureau's 2020 file of surnames carried by 100 people or more, no entry runs past 15 letters. The most common single name of that length is Balasubramanian, at rank 13,078; Riemenschneider and Balasubramaniam follow.

How many letters make a last name long?

This list starts at 12 letters, our own cut. Of the 156,621 surnames in the file, 2,492 are that long or longer, fewer than two in every hundred, and about 740 of those are two common surnames run together.

Are these long last names real?

Yes. Every name is in the Census Bureau's public file with its rank and its count, and each is carried by at least 269 people. Only the draw is random.

Why is a name written Vandenheuvel and not Van den Heuvel?

The file stores each name as one word in capitals, without spaces, hyphens or accents. The list prints it with a single capital and puts back only Mc, Mac and O' forms, so families who write Van den Heuvel or Röthlisberger see Vandenheuvel and Rothlisberger.

How this list was compiled: A list by a written rule, built on 2 October 2026 from the US Census Bureau's file of last names reported 100 or more times in the 2020 Census (https://www2.census.gov/topics/genealogy/2020surnames/Names2020_LastNames_RaceHispanic.xlsx, linked from https://www.census.gov/topics/population/genealogy/data/2020_names.html), read that day: 156,621 names, of which 2,492 have 12 letters or more and none has more than 15. This list is the 600 most common of those, taken in the file's order of rank, from Hollingsworth (rank 1,529, 22,814 people) to Delagardelle (rank 76,963, 269 people). Names with the same count share a rank in the file. The bureau stores names in capitals with spaces, hyphens and apostrophes removed, so a double surname is stored as one word (GARCIAHERNANDEZ). Left out, by rule: an entry that is two surnames of the file's first 1,500 run together (526 such entries were passed over before the list was full; Kleinschmidt, Schwartzberg and Bergschneider are single German surnames and stay), and, as our own call, 11 entries that are usually written as two or more words or with a hyphen (those that begin with Jean, John or Saint followed by another name in the file, and Louisjacques, Delosangeles, Delatrinidad, Martindelcampo, Santodomingo). Everything else is printed with a single capital and without accents; the written form is put back only for the four names that start with Mc, for MacGillivray and for O'Shaughnessy, and particle names stay as the file has them (Vandenheuvel, Delahoussaye). The letter count is of the file's spelling. Where the surname has an entry on English Wiktionary whose etymology could be read as one plain sentence, the card adds the opening of that etymology (98 of the 600 cards; 28 of the first 100); a card that would say only that the name is a variant of another keeps the line only when that other name is on this list, and a card with no such entry gives the letter count, rank and count alone. An origin is what a dictionary records for the surname in general, not for any one family. Only the rank and count columns of the file are used; its race and Hispanic-origin columns are not used anywhere on the page.
