Dayron is a modern name that is especially common in Cuba, where inventive spellings of English-sounding names became fashionable in the late 20th century; it is usually read as a variant of Darren or Darron, a name of uncertain origin often linked to the Irish Darragh, "oak tree". Olympic hurdler Dayron Robles is its best-known bearer. In the United States Dayron is rare, peaking at number 2352 in 2024 and ranking number 2773 in 2025.
