Solid Air is the fourth studio album by Scottish singer-songwriter John Martyn, released in February 1973 by Island Records.

The album was recorded over eight days and features instrumental contributions by bassist Danny Thompson and members of Fairport Convention.

[5][6] "Solid Air", the title track, was dedicated to a friend of Martyn's, Nick Drake, who would die of an antidepressant overdose 18 months after the album was released.

Solid Air was given a further remastering and repackaging when a double CD reissue curated by John Hillarby was released in 2009, and which included several alternate studio and live versions.

In 2006, Martyn performed the album live in its entirety as part of the All Tomorrow's Parties-curated Don't Look Back series and subsequently toured the UK.
