Cumpleaños Feliz is the Spanish-language version of the Happy Birthday song, sung at birthday celebrations across Spain and Latin America. The melody is the same one used in English-speaking countries, while the Spanish words make it the standard greeting for birthdays in Spanish-speaking homes, schools, and restaurants. As short birthday clips spread through messaging apps, social media, and video edits, this version became a convenient way to send warm wishes in Spanish without recording a performance. It remains popular because the tune is instantly recognised, the words are simple, and the sentiment works for friends, family, and colleagues alike.
