We report on observations of the candidate Be/X-ray binary IGR J18219$-$1347with \textit{Swift}/XRT, \textit{NuSTAR}, and \textit{NICER} during Type-Ioutbursts in March and June 2020. Our timing analysis revealed the spin periodof a neutron star with $P_\textrm{spin}=52.46$ s. This periodicity, combinedwith the known orbital period of $72.4$ d, indicates that the system is aBeXRB. Furthermore, by comparing the infrared counterpart's spectral energydistribution to known BeXRBs, we confirm this classification and set a distanceof approximately $10-15$ kpc for the source. The source's broadband X-rayspectrum ($1.5-50$ keV) is described by an absorbed power-law with photon index$\Gamma$\,$\sim$\,$0.5$ and cutoff energy at $\sim$\,$13$ keV.
