The Iberian Romance, Ibero-Romance or sometimes Iberian languages are a group of Romance languages that developed on the Iberian Peninsula, an area consisting primarily of Spain, Portugal, Gibraltar, Andorra and French Catalonia. They are today more commonly separated into West Iberian, East Iberian (Catalan/Valencian) and Mozarabic language groups. East Iberian's classification is a subject of ongoing scholarly debate, as some argue that the Occitano-Romance languages composed of Occitan along with the aforementioned two are better classified as Gallo-Romance languages.

Evolved from the Vulgar Latin of Iberia, the most widely spoken Iberian Romance languages are Spanish and Portuguese, followed by Catalan-Valencian-Balear and Galician. These languages also have their own regional and local varieties. Based on mutual intelligibility, Dalby counts seven "outer" languages, or language groups: Galician-Portuguese, Spanish, Asturleonese, "Wider"-Aragonese, "Wider"-Catalan, Provençal+Lengadocian, and "Wider"-Gascon.

In addition to those languages, there are a number of Portuguese-based creole languages and Spanish-based creole languages, for instance Papiamento.

Like all Romance languages, the Iberian Romance languages descend from Vulgar Latin, the nonstandard (in contrast to Classical Latin) form of the Latin language spoken by soldiers and merchants throughout the Roman Empire. With the expansion of the empire, Vulgar Latin came to be spoken by inhabitants of the various Roman-controlled territories. Latin and its descendants have been spoken in Iberia since the Punic Wars, when the Romans conquered the territory (see Roman conquest of Hispania).

The modern Iberian Romance languages were formed roughly through the following process:

This list points to common traits of these Iberian subsets, especially when compared to the other Romance languages in general. Thus, changes such as Catalan vuit/huit and Portuguese oito vs. Spanish ocho are not shown here, as the change -it- > -ch- is exclusive to Spanish among the Iberian Romance languages.

Politically (not linguistically), there are four major officially recognised Iberian Romance languages:

Additionally, Asturian (dialect of Asturleonese), although not an official language, is recognised by the autonomous community of Asturias. It is one of the Asturleonese dialects along with Mirandese, which in Portugal holds an official status as a minority language.
