Origin
The surname MacKinnon originated in Scotland, with the earliest known records dating back to the late 13th century. The name is derived from the Gaelic "Mac Ionmhuinn," which translates to "son of the beloved one." It is believed that the MacKinnons were originally a branch of the larger Clan Donald, one of the most prominent clans in the Scottish Highlands.
The MacKinnons were historically centered in the Hebrides, an archipelago off the western coast of Scotland. They held lands on the islands of Mull, Iona, and Skye, as well as in the mainland region of Kintyre. The name is thought to have first appeared in written records around 1292, when a Gillecalum M'Cenychin is mentioned in the Exchequer Rolls of Scotland.
One of the earliest notable figures associated with the MacKinnon name was John MacKinnon, who lived in the late 14th century and served as the Chief of the Clan MacKinnon. He is recorded as having been present at the Battle of Harlaw in 1411, which was a significant conflict between the forces of the Duke of Albany and the Earl of Mar.
Another prominent MacKinnon was Lachlan Mor MacKinnon, who lived in the late 16th and early 17th centuries. He was a respected clan chief and is credited with establishing the MacKinnon seat at Kilmorie on the Isle of Skye. Lachlan Mor was also involved in the political and military affairs of the time, supporting the Royalist cause during the Scottish Civil War.
In the 18th century, Daniel MacKinnon (1722-1797) was a notable figure who served as a captain in the British Royal Navy. He participated in several significant naval battles during the Seven Years' War and the American Revolutionary War, earning recognition for his bravery and leadership.
Perhaps the most famous bearer of the MacKinnon name was Sir William Alexander Mackinnon (1832-1897), a Scottish businessman and politician. He co-founded the British India Steam Navigation Company and was instrumental in the development of trade and transportation routes between Britain and its colonies. Mackinnon was also a member of the British Parliament and was knighted for his contributions to the British Empire.
Throughout history, the MacKinnon surname has been spelled in various ways, including MacKinnon, MacKynnon, MacKinon, and MacKinnen, among others. This diversity in spelling reflects the evolution of the name over time and its adaptation to different regions and dialects within Scotland.
Demographics
Among Census respondents with the surname Mackinnon, the largest self-reported group is White at 90.6%. The next largest groups are Hispanic (3.9%) and Two or More Races (3.2%).
The bar chart below shows how Mackinnon 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 Mackinnon 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 Mackinnon (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.
