Boy Names Starting With X

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 X boy names in the generator, or browse the full top 100 boy names.

How common X names are

2 of the 1,000 most-registered boy names of 2025 start with X, and together they account for 0.33% of the births in that list — the 23rd-largest share among the 26 initials. From Xavier at overall #108 (3,232 births) down to Xilo, the 50th name, at #8,879 (9), the first count on the table is 359.1 times the last.

That 0.33% is X'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.

X names across the decades

X has no boy name inside the top 200 in 1955, 1965, 1975, and 1985; the first snapshot with one is 1995, when Xavier (#148) charted. The high of 1 is shared by 1995, 2005, and 2015, so the last snapshot, 2015, sits at that high, led by Xavier (#90). Cut to the same top-200 depth, the 2025 list holds 1 X name, led by Xavier at #108. Xavier is the leading X name in every snapshot where the letter appears in the top 200 (3 of 7). No name on the 2025 X table appears in all 7 snapshot top-200 lists.

X names held 0.00% of the top-200 births for boys in 1955 and 0.42% in 2015; at the same depth in 2025 the figure is 0.36%. The first-letter trends guide sets X's share beside the other 25 initials for every snapshot year from 1955 to 2015, for both sexes.

Faded and new

Every X boy name that appears in any snapshot's top 200 is also on the 2025 list of 50 above, so no faded names exist for this letter at the committed depths.

Of the 50 names above, 49 appear in none of the 7 snapshot top-200 lists: the first 12 by rank are Xander (#259), Xaden (#1,420), Xzavier (#1,485), Xavi (#1,545), Xaiden (#1,675), Xavian (#1,768), Xavion (#1,790), Xion (#1,791), Xyleek (#1,792), Xylo (#1,903), Xayden (#1,975), and Xyaire (#2,360), and the remaining 37 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 X's 50th name (#8,879), 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

Medium spellings of five to seven letters account for 38 of the 50 names on the 2025 list (Xavier, for one); 11 are short at four letters or fewer (Xavi, for one), and 1 run to eight letters or more (Xzayvier, for one). The longest spelling on the 2025 list is Xzayvier at 8 letters and the shortest is Xen at 3.

By popularity tier, the list holds 0 top-10 names, 0 more inside the top 100, 2 in the 101–500 band, and 0 in the 501–1,000 band; 48 sit past #1,000, outside the top-1,000 list the generator's 2025 era draws from.

X gives the two sexes no shared spelling at these depths: none of this list's 50 names is among the 50 on the 2025 girls' X page. 25 of the 50 spellings on the 2025 list open Xa-, the letter's most common second letter, ahead of Xy- (12), and 7 different second letters appear across the list.
