Vaalbara is the name of Earth's first supercontinent, in the Archaean era.

Vaalbara started to form about 3,600 million years ago (mya). It formed by about 3,100 mya and broke up by 2,500 mya. The name Vaalbara comes from the South African Kaapvaal craton and the West Australian Pilbara craton. These cratons were combined in the Vaalbara supercontinent.
