American last names are a living map of history. They carry the fingerprints of English colonists, West African ancestors brought here by force, German and Irish immigrants fleeing famine and upheaval, Spanish settlers who were here before the United States existed, and waves of newcomers from every corner of the world. The most common american last names today reflect all of that layering, and the stories behind them are far more interesting than most people expect.
This list covers the 100 most frequently occurring surnames in the United States, grouped by origin and meaning. Each entry explains where the name came from and what it actually meant to the people who first carried it. Whether you are researching your own family history, building a character, or just curious, these are the names that show up most in American life.
English Occupational Surnames
A huge share of the most common American last names are English surnames that described what an ancestor did for work. These names traveled to America with the earliest English-speaking settlers and have been here ever since.
Smith
The single most common surname in the United States, full stop. It comes from the Old English smið, meaning a metalworker or craftsman. Every village in medieval England had a smith, which is exactly why the name is so widespread.
Johnson
A patronymic meaning “son of John,” Johnson is the second most common surname in America. It took firm root in both English and Scandinavian traditions, and it is also one of the most common surnames among African Americans, adopted by formerly enslaved people after emancipation.
Williams
Williams means “son of William,” derived from the Germanic name Wilhelm, meaning “will” and “helmet” or “protection.” It arrived in England with the Normans after 1066 and became one of the most persistent surnames in the English-speaking world.
Brown
Originally a nickname for someone with brown hair, a brown complexion, or a habit of wearing brown clothing. Old English brun is the root. It crossed into surname use naturally, and today it sits comfortably among the top five American last names.
Jones
The Welsh and English form of “son of John,” Jones is especially dominant in Wales but has been a top-ten American surname for generations. John itself traces back through Latin and Greek to the Hebrew Yohanan, meaning “God is gracious.”
Miller
An occupational name for someone who operated a grain mill. It has English, German (Mueller/Müller), and Dutch (Molenaar, simplified on arrival) roots, all converging on the same job. Its presence at the top of American surname lists reflects how essential mills were to early communities.
Davis
A patronymic meaning “son of David,” from the Hebrew name Dawid, meaning “beloved.” Davis was especially common in Wales and western England and came to America with early settlers. It is also among the most common surnames in the African American community.
Wilson
Means “son of Will” or “son of William,” from the medieval short form Will. It was widely used in northern England and Scotland and has been a consistent top-ten American surname for well over a century.
Moore
This one has two separate origins that merged under the same spelling. It can describe someone who lived near a moor (open, boggy land) from Old English mor, or it can be a nickname from Old French more, meaning dark-complexioned. Both streams fed into the same common American name.
Taylor
From the Old French tailleur, a cutter of cloth, meaning a tailor. It arrived in England after the Norman Conquest and became one of the most common occupational surnames in the language. Today it is also widely used as a first name.
Anderson
Means “son of Andrew,” from the Greek name Andreas, meaning “manly” or “strong.” It is one of the most common surnames in both Scotland and Scandinavia, and Scandinavian immigrants of the 19th century helped push it into the top ranks of American last names.
Thomas
From the Aramaic name Toma, meaning “twin.” It entered English through the New Testament apostle and became both a popular given name and a common surname. As a last name it functions as a patronymic: son of Thomas.
Jackson
Means “son of Jack,” where Jack is a medieval pet form of John. It is a top-ten American surname and carries an especially rich presence in African American naming culture, in part because enslaved people were sometimes given the surname of their enslaver, and Jackson was a common one.
White
A descriptive surname from Old English hwit, applied to someone with fair hair or a pale complexion. Like Brown and Black, it belongs to a large family of color-based English nicknames that became inherited surnames.
Harris
A patronymic meaning “son of Harry,” where Harry is the English vernacular form of Henry. Henry itself comes from the Germanic Heimrich, meaning “home ruler.” Harris has been common in England for centuries and is well represented across all American communities.
Martin
From the Latin name Martinus, derived from Mars, the Roman god of war. It was enormously popular in medieval Europe because of Saint Martin of Tours, and it spread across England, France, Germany, and Spain. In America it draws from all of those traditions.
Thompson
Means “son of Thom,” a medieval short form of Thomas. The p crept in during the Middle Ages as a phonetic addition. It is one of the most common surnames in England and Scotland and has held a firm place in American surname lists for generations.
Garcia
One of the most common Spanish surnames in the world, Garcia is of uncertain but likely Basque origin. Some scholars connect it to a Basque word meaning “young” or “bear,” though the exact root is debated. In America it sits among the top ten most common surnames overall, reflecting the size and history of the Latino population.

Walker
An occupational surname for a “walker,” someone who trampled or fulled cloth in the wool-making process by walking on it. It is a specifically English trade name with no real equivalent in other languages, which makes its American prevalence a direct marker of English colonial heritage.

How to Use This List
If you are researching your family history, the origin section for each name here gives you a starting point for understanding which part of the world your ancestors likely came from. An English occupational name like Smith or Walker points toward English colonial roots. A name like Murphy or Sullivan points toward Irish immigration. Garcia, Martinez, and Flores point toward Spanish or Latin American heritage.
It is worth knowing that many American last names were changed, shortened, or anglicized at points of entry, particularly during the 19th and early 20th century immigration waves. A family named Mueller often became Miller. Families named Schmidt became Smith. Understanding the “translated” or anglicized form of your name can open up genealogical research that would otherwise hit a wall.
For writers naming characters, these common American last names are useful precisely because they are recognizable without being cliche. A character named James Walker or Maria Torres reads as real and grounded. The most common american last names are common for a reason: they have been doing this work for a long time, and they do it well.
Finally, if you are expecting a child and considering a surname-style first name, many of the names on this list work beautifully in that role. Anderson, Bennett, Campbell, Collins, Hayes, Morgan, Parker, and Russell are all surnames that have crossed over into given-name territory with genuine success. The line between first name and last name in American naming culture has always been more flexible than people think.
