What Does Kennedy Mean?
Kennedy is an Anglicized Gaelic name that is most often interpreted as meaning “Helmeted head.”
The etymology is fascinating and slightly debated among linguists. The name is derived from the Anglicized spelling of the Irish Gaelic surname Ó Cinnéidigh. This compound name breaks down into two distinct elements:
When combined, the direct translation suggests a head covered in armor, hence the “Helmeted Head” definition.
The Nuance of “Misshapen Head”
It is important for parents to know that some etymologists translate the second element not as éide (armor), but as éidigh, which means “ugly” or “misshapen.” In ancient Irish naming traditions, giving a child a name with a humble or descriptive meaning (like “Broad Head” or “Misshapen Head”) was common and not considered an insult. However, in modern contexts, the “Helmeted Head” (implying a warrior ready for battle) is the widely accepted and preferred meaning.
Where Does the Name Kennedy Come From?
Kennedy is distinctly Irish. It began as a surname to denote the descendants of Cinnétig mac Lorcáin, a 10th-century King of Thomond and the father of the legendary High King of Ireland, Brian Boru (3).
The name remained a prominent surname in Ireland and eventually traveled to North America with Irish immigrants. It entered the American consciousness as a given name largely due to the immense fame of the Kennedy political dynasty. It began to appear on birth certificates as a first name in the mid-20th century, initially as a tribute to President John F. Kennedy, before evolving into the style icon it is today.
How Popular is the Name Kennedy?
The popularity of Kennedy tells a tale of two genders. While it started as a male-leaning tribute name, it has transformed into a powerhouse name for girls.
Kennedy for Girls
Kennedy is currently a modern hit for girls. After entering the top 1000 in the early 1990s, it skyrocketed up the charts, fueled by the trend of using surnames as first names (like Taylor or Madison). It cracked the Top 100 in 2011 and has remained there comfortably since. It is a staple choice in the US, suggesting it is not just a passing fad but a defined style for this generation (4).
Kennedy for Boys
For boys, Kennedy is considered a rare gem. It saw a brief spike in the 1960s (following the presidency of JFK) and a smaller resurgence in the 90s, likely riding the coattails of the grunge/alternative wave. However, in recent years, it has fallen out of the Top 1000 for boys entirely. This makes it a unique, vintage-cool choice for parents of sons who want something recognizable but statistically uncommon.
How Do I Pronounce Kennedy?
The standard American pronunciation is KEN-nuh-dee.
- Syllables: Three (Ken-ne-dy)
- Emphasis: On the first syllable (KEN).
- Middle Sound: The middle “e” is usually a schwa sound (uh), though some pronounce it crisply as “ih” (KEN-nih-dee).
Is Kennedy a Boy or Girl Name?
Kennedy is a gender-neutral name, though usage in the 21st century leans heavily feminine.
Statistically, over 95% of babies named Kennedy in the US today are girls. However, because it is a surname, it retains a rugged neutrality that prevents it from feeling overly frilly. It sits in the same category as names like Rowan, Quinn, or Avery, names that are widely accepted for any gender, regardless of which way the charts lean.

- Cinnéidigh: (Irish Gaelic) The traditional spelling.
