The Most Common Surnames in the World

Across the globe, certain surnames stand out not just for their frequency, but for the rich cultural histories behind them. Leading the list is Nguyen, a name carried by an estimated 38 million people—most notably in Vietnam, where it’s so common it’s almost a default family name. Its prevalence stems from centuries of history, including royal dynasties and periods when commoners were assigned the name en masse.

Next is Silva, shared by around 32 million individuals, particularly in Portuguese-speaking countries like Brazil and Portugal. Meaning “forest” or “woods,” it reflects a tradition of naming based on geography or nature. Similarly, Garcia, with roughly 16 million bearers, is a staple across Spain and Latin America. Once a medieval first name, Garcia evolved into a surname and spread widely through migration and colonization.

In Muslim-majority regions, names like Mohamed and Ali are widespread, often tied to religious reverence. Mohamed, carried by an estimated 15 million, appears in various spellings across North Africa, the Middle East, and South Asia. Meanwhile, Kim, one of Korea’s most common surnames, belongs to about 12 million people—nearly a quarter of South Korea’s population—highlighting the country’s strong clan-based heritage.

Eastern Europe contributes Ivanov, a patronymic name meaning “son of Ivan,” found in Russia, Bulgaria, and beyond. And in English-speaking countries, Smith remains iconic—used by around 4 million—originating from the occupation of metalworking, once one of the most vital trades.

These names are more than labels—they’re threads connecting millions through lineage, language, and legacy. Their global spread tells a story of empires, migration, and the quiet persistence of identity across generations.
