Origin
The surname Gauthier originates from France and is derived from the ancient Germanic personal name Walther, which means "ruler of the army" or "commander of the host". This name was introduced into France by the Franks during the 5th century.
The name Gauthier is a variant of the more common French surname Gaultier, with the "au" spelling reflecting the Norman French influence. It was particularly prevalent in the northern regions of France, such as Normandy and Picardy, where the Norman language had a strong presence.
One of the earliest recorded instances of the name Gauthier can be found in the Domesday Book of 1086, which recorded landowners in England after the Norman Conquest. The name appears as Gauterius, referring to a Norman landowner in Gloucestershire.
During the Middle Ages, the name Gauthier was borne by several notable figures. Jean Gauthier (c. 1200-1272) was a French theologian and philosopher who taught at the University of Paris. Gauthier de Châtillon (c. 1135-1201) was a French poet and ecclesiastic known for his Latin poetry.
In the 14th century, Gauthier de Metz (c. 1300-1365) was a renowned French architect who worked on several Gothic cathedrals, including the Cathedral of Reims. Gauthier de Bruges (c. 1350-1424) was a Flemish painter and one of the earliest practitioners of oil painting in the Netherlands.
During the Renaissance, Gauthier Lenet (1561-1629) was a French cleric and one of the founders of the Congregation of the Oratory in France. Gauthier de Costes (1515-1603) was a French writer and poet who served as a secretary to King Henry IV.
As the name spread across Europe, it took on various spellings and forms. In Italy, it became Gualtieri, while in Germany, it was rendered as Walter or Walther. The Spanish variant is Galter, and the Portuguese form is Gualter.
Throughout history, the surname Gauthier has been associated with several notable individuals from various fields, including arts, literature, religion, and architecture. Its origins can be traced back to the ancient Germanic name Walther, reflecting the influence of the Franks on the French language and culture.
Demographics
Among Census respondents with the surname Gauthier, the largest self-reported group is White at 84.3%. The next largest groups are Black (6.3%) and Hispanic (4.0%).
The bar chart below shows how Gauthier 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 Gauthier 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.

For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
