A Persian name meaning "universe" or "cosmos."
Kayhan is a name of ancient Persian origin, derived from the Old Iranian word meaning 'universe,' 'cosmos,' or 'the world.' It belongs to the grand tradition of Persian names that locate the bearer within a vast, cosmic frame — a naming philosophy shared with words like Jahan (world) and Mehr (sun). The name carries the weight of Persian classical literature, where the cosmos was not merely astronomical but moral and spiritual: an ordered, beautiful whole in which human life had meaning.
Across Persian-speaking cultures — Iran, Afghanistan, Tajikistan, and diaspora communities worldwide — Kayhan has long been a given name for boys, evoking both ambition and wonder. The Iranian newspaper Kayhan, founded in 1942, bears the name as a statement of broad national scope. In literary and intellectual circles, the name conjures figures of expansive thought, people who see the big picture rather than the small.
In contemporary usage, Kayhan has gained quiet appreciation beyond the Persian-speaking world, particularly among families who want a name that sounds melodic in English ears while carrying deep cultural roots. Its soft opening syllable and open ending give it a modern feel without sacrificing its millennia-old heritage. For a child named Kayhan, they carry with them the idea that they are, in some sense, as large as everything.
