Origin
The surname Vaillancourt has its origins in France, dating back to the medieval period. It is a locational name derived from the French place name Vaillancourt, which itself comes from the Latin phrase "vallis anchorita," meaning "valley of the hermit."
One of the earliest recorded instances of the name Vaillancourt can be found in the Livre des Censiers, a medieval French document from the 13th century. This text mentions a person named Guillaume de Vaillancourt, who lived in the region of Normandy.
By the 16th century, the name had spread to other parts of France, as evidenced by records such as the Registres Paroissiaux, which document births, marriages, and deaths in various parishes. Notable individuals from this time period include Jean Vaillancourt (1532-1597), a merchant from Lyon, and Marie Vaillancourt (1568-1642), a landowner in the region of Burgundy.
During the 17th and 18th centuries, several Vaillancourt families emigrated from France to New France (now Canada). One of the earliest recorded arrivals was Michel Vaillancourt (1635-1712), who settled in the colony of Acadia in 1670. His descendants can be traced through the Acadian census records of the time.
In the 19th century, the Vaillancourt name gained recognition through individuals such as Joseph Vaillancourt (1819-1899), a prominent businessman and politician in Quebec, and Pierre Vaillancourt (1842-1923), a renowned architect who designed several churches and public buildings in the province.
Other notable figures with the surname Vaillancourt include:
1. René Vaillancourt (1901-1978), a Canadian painter and sculptor known for his abstract works.
2. Pauline Vaillancourt (1924-2005), a French-Canadian author and educator who wrote extensively on Quebec culture and history.
3. Claude Vaillancourt (1933-2018), a Canadian actor and director who appeared in numerous films and television shows.
4. Françoise Vaillancourt (born 1951), a Quebec journalist and television host who has worked for various media outlets in Canada.
5. Martin Vaillancourt (born 1967), a Canadian ice hockey player who played in the National Hockey League for several teams.
Demographics
Among Census respondents with the surname Vaillancourt, the largest self-reported group is White at 92.6%. The next largest groups are Two or More Races (3.5%) and Hispanic (3.0%).
The bar chart below shows how Vaillancourt 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 Vaillancourt surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Vaillancourt (2000, 2010, 2020).
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.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. 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.
