The electron paramagnetic resonance (EPR) of the Eu<sup>2+</sup>+ ion in SrCl<sub>2</sub>:Eu single crystal has been investigated using an X-band spectrometer. The angular dependence of magnetic resonance positions for the Eu<sup>2+</sup>+ impurity ion in the crystallographic aa-plane is analyzed with effective spin-Hamiltonian. The EPR spectra of the isolated Eu<sup>2+</sup>+ center merged to each other. The hyperfine splitting of the isolated Eu<sup>2+</sup>+ center due to the 151Eu nucleus is approximately 35 G. Three kinds of Eu<sup>2+</sup>+ centers except the isolated Eu<sup>2+</sup>+ center, Eu<sup>2+</sup>+ pairs, Eu<sup>2+</sup>+ triples, and other Eu<sup>2+</sup>+ clusters, are split from the fitting of the integrated experimental spectrum with the Gaussian curve. The calculated spectroscopic splitting parameters of the Eu<sup>2+</sup>+ pairs, Eu<sup>2+</sup>+ triples, and other Eu<sup>2+</sup>+ clusters in SrCl<sub>2</sub>:Eu crystal are g<sub>1</sub> = 2.06, g<sub>2</sub> = 1.94, and g<sub>3</sub> = 1.93, respectively.
