Among the most famous of these are the Seville Fair or Feria de Abril in Seville, now echoed by smaller fairs in Madrid and Barcelona, both of which have many Andalusian immigrants; the Feria de Agosto in Málaga; the Feria de Jerez or Feria del Caballo in Jerez; the Festival of Corpus Christi in Granada; the Feria de Nuestra Señora de la Salud in Córdoba; the Columbian Festivals (Fiestas Colombinas) in Huelva; the Feria de la Virgen del Mar in Almería; and the Feria de San Lucas in Jaén, among many others.

Atlantic bluefin tuna (Thunnus thynnus) from the Almadraba areas of the Gulf of Cádiz, prawns from Sanlúcar de Barrameda (known as langostino de Sanlúcar), and deepwater rose shrimp () from Huelva are all highly prized.
