Every name below comes with its meaning and origin so you can pick with confidence.

Most Common Last Names in the US

The most common last names in America reflect centuries of immigration. Occupational names like Smith and Miller sit alongside patronymics like Johnson and Davis, plus Spanish surnames such as Garcia and Rodriguez that mirror the country’s growing Hispanic heritage. According to the U.S. Census Bureau’s surname data, the top names have barely changed in decades — a sign of how deeply rooted family names are.

Many of these started as simple job titles or family markers. A “Smith” was literally the village blacksmith, while a “Johnson” was known as John’s son. Over generations, these labels stuck and became permanent family names. You can track how name popularity shifts over time on the Social Security Administration’s baby names page, which publishes yearly naming data.

German Last Names

German surnames are famously practical — they name the job you did. Schmidt, Schneider, and Weber are all trade names.

Spanish Last Names

Spanish surnames lean heavily on patronymics — the “-ez” ending means “son of.” Rodriguez, Hernandez, and Lopez all follow this pattern.

Last Names Now Used as First Names

One of the biggest naming trends of the last few decades is the surname-to-first-name crossover. Names like Madison, Carter, and Harper started as family names and now top baby name charts. Parents love them because they sound strong, modern, and gender-neutral. They also make fun nicknames for your family group chat names.

Where Do Last Names Come From?

Most last names fall into four buckets. Occupational names describe a job: Smith, Miller, and Schmidt. Patronymic names name the father: Johnson, Rodriguez, and O’Brien. Descriptive names describe a person: Brown, Rossi, and Kelly. Place names mark where someone lived: Ashford, Fontaine, and Tanaka.

Fixed family names are surprisingly recent in many cultures. England only made surnames standard after the Norman Conquest, and some regions — like parts of Iceland and Southeast Asia — still use patronymic systems today, where the “last name” changes every generation. That is why researching your surname is really researching your family’s story.

Frequently Asked Questions

What is the most common last name in the US?

Smith is the most common last name in the United States, held by over two million people. It comes from the Old English word for a metalworker or blacksmith. Johnson and Williams round out the top three, according to U.S. Census surname data.

What is the difference between a last name and a surname?

There is no difference — “last name,” “surname,” and “family name” all mean the inherited name shared by a family. One note: in many East Asian cultures, including China, Japan, and Korea, the family name is written and spoken first, before the given name.

How can I find out what my last name means?

Start with the origin categories above: check whether your name looks occupational, patronymic, descriptive, or geographic. Then look up its etymology in a surname dictionary or genealogy database. Variant spellings are common, so search a few versions of your name.

Why are so many last names used as first names now?

The trend took off in the 1990s and 2000s as parents sought fresh, strong-sounding names. Surnames like Madison, Carter, and Harper feel modern and work well for any gender, which keeps them climbing on baby name charts tracked by the Social Security Administration.

Can I legally change my last name?

Yes, in most countries you can change your last name through a court petition or, in some cases, simply by using a new name consistently. Requirements vary by state and country, so check your local laws before starting the process.
