We present results for the elemental abundances of five K giants of the young open cluster NGC 2345. The atmospheric parameters of the studied giants and their chemical abundances were determined using high-resolution optical spectroscopy. In this study, we determine abundances of light elements (Li, C, N), light odd-Z elements (Na, Al), α-elements (Mg, Si, Ca, Ti), Fe-group elements (Cr, Fe, Ni), and n-capture elements (Y, Zr, La, Ce, Nd, Sm, Eu) for each star. Abundances of the light elements and Eu were obtained using spectral synthesis technique. Also, rotation velocities were determined through the spectral synthesis of the Fe I line at 6151.6 Å. The mean metallicity obtained for the open cluster is [Fe/H] = -0.33 ± 0.05 and it is considered low compared to recent studies for open clusters in the Milky Way, although low for its Galactic latitude (b = -02.31°). Lastly, the abundance analysis shows that there is good agreement with the profile of field clump stars with the same metallicity.
