1001° Centigrades, alternative title 2, is the second album by French rock band Magma, released on 5 October 1971.

The first track, "Rïah Sahïltaahk", was later re-recorded as a full-length studio album, Rïah Sahïltaahk, in 2014, as Christian Vander did not consider himself satisfied with the arrangement on this album.

For this album,Magma underwent several personnel changes: guitarist Claude Engel departed without being replaced, and Alain Charlery and Richard Raux made way for Louis Toesca (trumpet) and Yochk'o Seffer (sax, bass clarinet).

With lyrics again performed in the band's invented language, the album chronicles the Kobaïan people's return to Earth to save the planet.On 1001° Centigrades the "zeuhl" sound that later came to define Magma develops, but it lacks the operatic female vocals and primal driving rhythm of the following album, Mëkanïk Dëstruktïẁ Kömmandöh.

Two (saxophonist Yochk'o Seffer and keyboardist François Cahen) left to form Zao, a band which follows in the footsteps of Magma's first two releases.
