Origin
Meaning and origin of Hermawan
The surname Hermawan originates from Indonesia, where it has been in use since at least the 16th century. It is derived from the Old Javanese words "heru" meaning "leader" and "mawan" meaning "brave", together forming a name meaning "brave leader".
The name was particularly prevalent in the central and eastern regions of Java, where it was commonly held by local nobility and warriors. Variants like Hermawan, Hermawan, and Hermawan were also found in historical records from this era.
One of the earliest known bearers of the name was Raden Hermawan, a 16th century Javanese military commander who served under the Sultan of Demak. His exploits are documented in the Babad Tanah Jawi, an important Javanese literary work.
In the 17th century, the village of Hermawan in what is now Yogyakarta was named after a local noble bearing this surname. The 1785 Serat Centini manuscript mentions a character named Ki Hermawan who was a respected elder.
Notable people with this surname include Hermawan Susanto (1916-1992), an Indonesian economist and professor, and Hermawan Rachmatullah (born 1967), a former Indonesian national football player. Adi Hermawan (born 1972) is a contemporary Indonesian singer and actor.
Raden Mas Arya Hermawan (1890-1963) was a Javanese prince and independence activist against Dutch colonial rule. The spelling Hermawan was sometimes used for this individual in Dutch records from the era.
Across its centuries of recorded use in Indonesia, the name Hermawan has consistently been associated with bravery, leadership, and the island's rich cultural heritage.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Hermawan surname at the time of the 2020 Census, not any inherent property of the name itself.
