Meaning
variant of Kilian, 'church' / 'little churchman'
The story
Kylian is the French spelling of the Irish Cillian, traditionally linked to the meaning little church; Saint Kilian was an Irish missionary bishop who died in seventh-century Germany and is still honored in Würzburg. The modern fame is all one man's. Kylian Mbappé burst into the 2018 World Cup as a teenager, scored in the final as France won it, struck a hat-trick in the astonishing 2022 final that France narrowly lost, and now captains his country while starring for Real Madrid. In France the name had already grown popular before he made it famous worldwide. In the United States it was essentially unused until this century, appearing and growing only in the last two decades, right alongside Mbappé's rise; we cannot prove the connection, but the timing is hard to ignore. Kylian remains a rare, distinctly French pick.

Poland

In Poland, 3 boys named Kylian were born in 2025, the 581st most common name among boys that year.
The count never rose above 3 in a year, too few to chart.
First names given to children born in Poland by year of birth, 2000–2025, from the PESEL population register (Ministry of Digital Affairs); exact spellings count separately (Łukasz and Lukasz are different names), names given fewer than 5 times in a year were left off the list through 2012 and fewer than 2 times from 2013, and the register also counts children born abroad, so its yearly sums run above Poland’s live births. Shares divide by the register’s own published total for the year, never by births. Source: Ministry of Digital Affairs, PESEL register (dane.gov.pl)
Brazil

At the 2022 census, 138 people in Brazil were named Kylian, ranked 32,928th, with a median age of 2.

Not on the record in New Zealand: that registry withholds small counts, so rare uses may sit below its floor.
Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years. Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
