Origin
The surname Rosenberg is of German origin, deriving from the words "rose" and "berg" which together mean "rose mountain" or "mountain of roses." It is believed to have originated in the 12th century, potentially referring to a person who lived near a rose-covered hill or a location known for cultivating roses.
One of the earliest recorded instances of the name Rosenberg can be found in the Codex Diplomaticus, a collection of medieval diplomatic documents from the 13th century, where it appears as "Rosenberger." This indicates that the name was already in use and well-established by that time.
In the 14th century, the Rosenberg family rose to prominence as a noble lineage in Bohemia, now part of the Czech Republic. They were feudal lords and held significant influence in the region, with their ancestral seat being the Rosenberg Castle near the town of Český Krumlov.
A notable figure from this family was Petr Vok of Rosenberg (1539-1611), a renowned patron of the arts and sciences who supported numerous scholars, artists, and alchemists during the Renaissance period.
The name Rosenberg also has a strong connection to the Jewish community, particularly in Germany and the Austro-Hungarian Empire. Many Jewish families adopted German surnames during the 18th and 19th centuries, and Rosenberg was one of the names chosen, possibly due to its association with nobility or as a reference to the rose's symbolic significance in Jewish culture.
One of the most famous individuals with the surname Rosenberg was Julius Rosenberg (1918-1953), an American engineer who, along with his wife Ethel Rosenberg, was convicted of passing information about the atomic bomb to the Soviet Union during the Cold War. Their controversial trial and execution sparked widespread debate and controversy.
Another prominent figure was Alfred Rosenberg (1893-1946), a German Nazi theorist and one of the principal architects of Nazi ideology. He served as the Reich Minister for the Occupied Eastern Territories during World War II and was convicted of war crimes at the Nuremberg Trials.
In the arts, Henri Rosenberg (1824-1904) was a renowned French art dealer and expert on Old Masters, while Marianne Rosenberg (born 1955) is a celebrated German singer and songwriter.
The name Rosenberg has also been associated with scientific achievements, such as Ralph Rosenberg (1866-1940), an American astronomer who made significant contributions to the study of galaxies and nebulae, and Hans Rosenberg (1904-1988), a German-American historian and scholar of modern European history.
Demographics
Among Census respondents with the surname Rosenberg, the largest self-reported group is White at 93.0%. The next largest groups are Hispanic (3.2%) and Two or More Races (2.0%).
The bar chart below shows how Rosenberg bearers described their own race and ethnicity on the 2020 Census form. 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 Rosenberg surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
