Vaalbara was an Archean supercontinent consisting of the Kaapvaal Craton and the Pilbara Craton . E.S. Cheney derived the name from the last four letters of each craton's name.

The two cratons consist of crust dating from 2.7 to 3.6 Gya, which would make Vaalbara one of Earth's earliest supercontinents. The evidence that Vaalbara (2.7-3.6 billion years ago) was the first supercontinent is mainly based on their sedimentary sequences and magnetic orientation. Supercontinent was a metal band from Ann Arbor, MI. Their first and only album, 'Vaalbara', was released in 2008.
