Meaning & origin
Quillan is a rare Irish-derived name that entered U.S. records in 1982, but it has never achieved widespread use. Its peak year was 2019, though it has been falling in popularity since 2018. With a rank of 12,008 in 2025 and a 1-in-341,615 birth rate, Quillan remains an uncommon choice. The name is primarily used for boys and has no recorded top states, indicating its scattered usage across the country.
Quillan likely derives from the Irish surname Ó Cuileáin, meaning 'descendant of Cuileán', a byname meaning 'little cub' or 'whelp'. In modern contexts, it has been used as a given name, possibly influenced by the similar sounding Quinn or the surname Quillan. The name first appeared in U.S. records in 1982 but remains rare.
