Adrian Albert Naef (born January 10, 1948) is a Swiss writer and musician.
One of his most known works is Nachtgängers Logik – Journal einer Odyssee (Suhrkamp 2003), a written statement of his struggle against a severe depression.
It is the first work of his literary comeback after 28 years, again by the same German publishing house as his debut work Lagebericht (Suhrkamp 1975).
