The Atlantic Bronze Age is a cultural complex of the Bronze Age period of approximately 1300–700 BC that includes different cultures in Portugal, Andalusia, Galicia, Armorica and the British Isles.

The Atlantic Bronze Age is marked by economic and cultural exchange, which lead to the high degree of cultural similarity exhibited by the coastal communities from Galicia to Scotland, including the frequent use of stones as chevaux-de-frise, the establishment of cliff castles, or the domestic architecture sometimes characterized by the round houses. Commercial contacts extend from Denmark to the Mediterranean. The period was defined by a number of distinct regional centres of metal production, unified by a regular maritime exchange of some of their products. The major centres were southern England and Ireland, north-western France, and north-western Iberia.

The items related to this culture are frequently found forming hoards, or either they are deposited in ritual areas, usually watery contexts: rivers, lakes and bogs. Among the more noted items belonging to this cultural complex we can count the socketed and double ring bronze axes, sometimes buried forming large hoards in Brittany and Galicia; war gear, as lunate spearheads, V-notched shields, and a variety of bronze swords —among them carp's-tongue ones— usually found deposited in lakes, rivers or rocky outcrops; and the elites feasting gear: articulated roasting spits, cauldrons, and flesh hooks, found from central Portugal to Scotland.

The Bronze Age is a period characterized by the use of copper and its alloy bronze as the chief hard materials in the manufacture of some implements and weapons. Chronologically, it stands between the Stone Age and Iron Age. The term Stone Age implies the inability to smelt any ore, the term Bronze Age implies the inability to smelt iron ore and the term Iron Age implies the ability to manufacture artifacts in any of the three types of hard material. Their arrangement in the archaeological chronology reflects the difficulty of manufacture in the history of technology.

During the past few centuries of detailed, scientific study of the Bronze Age, it has become clear that on the whole, the use of copper or bronze was only the most stable and therefore the most diagnostic part of a cluster of features marking the period. In addition to the creation of bronze from raw materials and the widespread use of bronze tools and weapons, the period continued development of pictogramic or ideogramic symbols and proto-writing, and other features of urban civilization.
