Mythimna l-album, the L-album wainscot, is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1767 12th edition of Systema Naturae. It is distributed throughout Europe, but is also found in North Africa from Morocco to Tunisia and in the Levant, then east across the Palearctic to Central Asia. It is not found in the far north of the Arabian Peninsula. The limit in the north varies. It occurs on the northern edge of the range as a migrant. From southern England, then Denmark and southern Scandinavia, the north limit cuts across the Baltic Sea across the Baltic states then south of Moscow to the Urals.
