  Unparticle contributions to the recently measured decay mode
$B_s\to\mu^+\mu^-$ are analyzed. We consider only the scalar unparticles
because vector unparticles are expected to provide negligible contributions.
Assuming that the relevant coupling constants are real, we present allowed
regions of coupling constants and the scaling dimension of the scalar
unparticle. While the measured value of the branching ratio is very close to
the standard model predictions, one cannot exclude the possible contributions
from unparticles.
