Boy Names Starting With U

Ranks are each name's overall position among all 2025 boy names, so the gaps between rows are real — the names in between simply start with other letters. Want a random shortlist instead? Spin U boy names in the generator, or browse the full top 100 boy names.

How common U names are

Measured by births, U is the 26th initial of 26 for boys in 2025: its 2 names inside the top 1,000 add up to 0.08% of that list's births. From Uriel at overall #446 (708 births) down to Uzay, the 50th name, at #13,746 (5), the first count on the table is 141.6 times the last.

That 0.08% is U's births inside the 2025 top 1,000 divided by the births of all 1,000 names — the convention the reading ranks and counts guide walks through — and the 2-name count is taken at that same depth, not at the 50-name depth of the table above.

U names across the decades

None of the 7 snapshot years, 1955 through 2015, has a boy name starting with U inside its top 200, so there is no decade table to show for this letter. Cut to the same top-200 depth, the 2025 list holds no U name at all — the letter's first entry that year, Uriel, sits at #446.

Because no U name reaches a top-200 list in any of those years, the letter's share of top-200 births is zero in every snapshot and in 2025 alike. The first-letter trends guide sets U's share beside the other 25 initials for every snapshot year from 1955 to 2015, for both sexes.

Faded and new

Because no U boy name reaches any snapshot's top 200, there is nothing to list as faded: the 7 snapshot files contain no U entries to set against the 2025 table.

All 50 names on the 2025 U list are absent from every snapshot top 200; the first 12 by rank are Uriel (#446), Uriah (#650), Ulises (#1,043), Umar (#1,164), Ulysses (#1,201), Uziel (#1,424), Usman (#1,607), Usher (#1,974), Uzziah (#2,225), Unknown (#2,757), Unique (#2,792), and Urijah (#2,876), and the remaining 38 follow in the table above.

Absence is relative to the committed depth: the snapshot files stop at rank 200 and the 2025 letter file stops at U's 50th name (#13,746), so a faded name may still be registered in 2025 below that point, and a newcomer may have been registered in a snapshot year below rank 200.

Shape of the list

3 of the 50 names on the 2025 list run to eight letters or more (Ugochukwu, for one), 10 stop at four or fewer (Umar, for one), and the remaining 37 sit in the five-to-seven-letter middle (Uriel, for one). The longest spelling on the 2025 list is Uchechukwu at 10 letters; the shortest, at 3, are Uri and Umi.

By popularity tier, the list holds 0 top-10 names, 0 more inside the top 100, 1 in the 101–500 band, and 1 in the 501–1,000 band; 48 sit past #1,000, outside the top-1,000 list the generator's 2025 era draws from.

Both sexes' 2025 U lists carry 6 of the same spellings, ranked once per sex: Uriel (#446 for boys, #9,422 for girls), Uriah (#650 for boys, #4,657 for girls), Unknown (#2,757 for boys, #3,293 for girls), Unique (#2,792 for boys, #2,456 for girls), Uriyah (#5,829 for boys, #8,322 for girls), and Umi (#13,745 for boys, #7,108 for girls). 10 of the 50 spellings on the 2025 list open Ur-, the letter's most common second letter, ahead of Ul- (8), and 14 different second letters appear across the list.
