Meaning & origin
Koy is an extraordinarily rare American given name whose origins remain obscure. It first appeared in Social Security records in 1970, and it has never climbed high on the charts, reaching its peak rank of 5,208 only in the latest year, 2025. The name's rarity means it is given to roughly 1 in every 94,893 boys, a figure that underscores its distinctive character. Koy's trajectory has been slowly rising since 1985, suggesting a quiet but steady increase in interest, though it has not yet recorded any top-state concentrations. Parents drawn to Koy may appreciate its brevity and modern sound, but they should be prepared for a name that carries little historical or etymological baggage.
Koy is a rare given name of uncertain derivation. It may be a variant spelling of Coy, itself a nickname or given name of unclear origin, or a modern coinage influenced by similar-sounding names. The name has been in occasional use in the United States since the 1970s, but it remains uncommon, with its highest recorded rank in the late 1990s.
