The Einang stone (Einangsteinen) is a rune stone near Fagernes, Norway. It bears an Elder Futhark inscription in Proto-Norse, dated to ca. the 4th century. It is the oldest rune stone still standing at its original location, and it may be the earliest inscription to mention the name runo "rune", possibly, as it appears in the singular, still used in the original sense "secret". The inscription reads:

[ek go]dagastiR runo faihido

[I, Go]dguest drew the secret

The first four letters have not survived and are conjectured, the personal name may also have been GudagastiR, or similar.
