The #1 most common surname in America is Smith.
With an estimated population of over 2.4 million people, Smith holds the top position as the most widespread last name across the United States. This enduring prevalence is largely due to its historical origins as an occupational surname, derived from the Old English word "smitan," meaning "to strike" or "to forge." Historically, a "smith" was a skilled craftsman who worked with metal, such as a blacksmith, silversmith, or goldsmith, making it a very common and essential profession across various communities. As surnames became hereditary, "Smith" was adopted by many families, leading to its widespread distribution today.
