Using $(2.712 \pm 0.014) \times 10^{9} ψ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of $ψ (3686) \to 3 ϕ$ decay with a significance larger than $10 σ$ . The branching fraction of this decay is determined to be $(1.46 \pm 0.05 \pm 0.17) \times 10^{- 5}$ , where the first uncertainty is statistical and the second is systematic. No significant structure is observed in the $ϕ ϕ$ invariant mass spectra.
