  An angular analysis of the rare decay $B^0_s\rightarrow\phi\mu^+\mu^-$ is
presented, using proton-proton collision data collected by the LHCb experiment
at centre-of-mass energies of $7$, $8$ and $13~\rm{TeV}$, corresponding to an
integrated luminosity of $8.4~\rm{fb}^{-1}$. The observables describing the
angular distributions of the decay $B^0_s\rightarrow\phi\mu^+\mu^-$ are
determined in regions of $q^2$, the square of the dimuon invariant mass. The
results are consistent with Standard Model predictions.
