K.A (Köhntarkösz Anteria) is the ninth studio album by French rock band Magma. The album was Magma's first full-length studio release in just under 20 years. The material was largely composed by drummer Christian Vander in 1973–74, and fragments of it can be heard on Magma's 1977 live album Inédits.

K.A is sung almost entirely in Magma's constructed language Kobaïan. This album is part of the Köhntarkösz cycle of albums.

Christian Vander revisited an old unrecorded composition and gave it a very succesfull modern-day reinterpretation Introducing a new group sound that blends the vintage "Da Zeuhl" elements from Magma's Kohntarkosz-era material and the engrossing cosmic jazz and massed vocals of Vander's later group, Offering. The lineup featured here is very similar to the one appearing on the 2001 live CD and DVD Theusz Hamtaakh La Trilogie au Trianon. The album is a must-have for die-hard fans and newcomers alike.

K.A. is now available as a remastered 2LP in a gatefold sleeve. The record is cut at 45rpm for the ultimate audio experience.
