Quinceañero is the Spanish term for a boy celebrating a comparable 15th-birthday milestone.
The feminine noun quinceañera traditionally identifies the girl being honored, while quinceañero is the masculine counterpart. Both words derive from quince, meaning 15, and refer to the age-based coming-of-age tradition rather than to a particular garment or dance.
The masculine form is less widely recognized internationally because the quinceañera tradition has historically been more strongly associated with girls. Boys’ celebrations may follow similar patterns, including formal clothing, family participation, music, and a reception.
Terminology varies by region and household. A quinceañero celebration may also be described with phrases such as quince años, so the exact wording used by a family is not universal.
