Baby Names by First Letter

The first letter sets a name’s whole tone — the soaring vowel of Aria, the crisp snap of Knox, the buzzing flair of Zoe. It is also one of the most practical ways to choose: matching a sibling’s initial, honouring a relative, or building a monogram. This guide sorts names into 26 buckets, one for every letter A to Z, and lists for each the real names that charted in the latest US Social Security figures.

Pick a letter to see every charting name that starts with it, ranked by US popularity, with each name’s gender and a link to its full meaning, origin, and popularity history. Every list is read straight from the 2024 birth data — want another angle? Try names by length, by syllable count, or by ending.

How these lists are built

Rather than guess which names start with a letter, we read it from the data. For each letter we pull every name that charted on the 2024 US Social Security list and begins with it, count each name once under the gender it is given to more often, and rank the results by national popularity. That keeps the lists honest and current: a name only appears here if real families used it that year, and the gender shown reflects how it is actually given. Spelling variants are treated as the different names they are, so Sophia and Zofia sit under different letters.

Browse names another way: by length, by syllable count, by ending, with double letters, or unisex & gender-neutral names.

Frequently asked questions

How does browsing baby names by first letter work?

Pick any letter from A to Z and you get every real name that begins with it and charted in the latest US Social Security data, ranked by popularity, with each name’s gender and a link to its full meaning and origin. It is a quick way to find names that match a sibling’s initial, an honoured family member, or a monogram you have in mind.

Where do these name lists come from?

Each letter page is built live from the 2024 US Social Security Administration birth data. We list the real names that charted that year and begin with the chosen letter, show each name’s national rank, and link to its full meaning and origin. Nothing is invented — a name only appears if real families used it.

Which letters start the most baby names?

A, J, M, and S open some of the largest fields of popular names, while Q, X, and U are the rarest first letters — so a name starting with one of those instantly feels more distinctive. Every letter A to Z has its own page here, so you can see exactly how many charting names each one carries.
