  We discuss the possible interpretation of the recently observed transient,
GN-z11-flash as originating from a shock-breakout in a Population III supernova
occurring in the GN-z11 galaxy at $z \sim 11$. We find that the parameters of
the explosion are fully consistent with those expected from the shock breakout
associated with a Type II supernova of a progenitor star of $\sim 300$ solar
masses in this galaxy, with of order unity such events expected over an
observing timescale of a few years. We forecast the expected number of such
transients from $z > 10$ galaxies as a function of their host stellar mass and
star formation rate.
