Random last names from 21 origins
The Last names mode picks from 419 real surnames. Each result shows the naming tradition it is most associated with, so you can keep a family or a fictional town consistent: Murphy and Gallagher are Irish, Rossi and Esposito Italian, Tanaka and Watanabe Japanese, Okafor and Adeyemi Nigerian. Many surnames are shared by several cultures; the label shows a common origin, not every one.

Surnames by origin
Origins help keep a fictional family, town or cast consistent. Many surnames began as a description: occupations (Smith, Baker, Müller is German for miller, Ferrari comes from the Italian for blacksmith), places (Hill, van den Berg, “from the mountain”), a father’s name (Johnson, Hansen, Rodriguez, Ivanov) or a nickname (Brown, Klein, “small”). Patronymic endings such as -son, -sen, -ez and -ov all mean “son of”.
For first names, or full names that pair a first name with a surname from the same culture, use the random name generator.
Frequently asked questions
Are these real last names?

Can I generate a last name from a specific country or culture?
Yes. Use the Origin filter to pick from 21 origins such as Irish, Italian, German, Chinese, Japanese, Indian or Nigerian. Many surnames exist in more than one culture, so the label shows a common origin.
Can I get a first name as well?
This page generates surnames only. The random name generator makes first names and full names, with a surname from the same origin as the first name.
Can I use the surnames as test data?
Yes. Generate up to 50 at once and export them as CSV or JSON to seed a last_name column or build a sample roster.
Will I get the same surname twice?
Not while No repeats is on. The generator works through every matching surname before any can repeat, and tells you when the list resets.
