UBVI CCD photometry of open cluster NGC 2324 is presented. C-M diagrams of this cluster show well-defined main sequence with a red giant clump centered at B - V =1.05, V =13.45. We derived the major cluster characteristics; E(B - V)=0.17$pm$0.12 from color-color diagram and mean color of red giant clump stars, (m - M)o=13.1$pm$0.1 from zero age main sequence fitting, and [Fe/H]$~$-0.32 from comparison the theoretical model developed by Bertelli et al. (1994) to the observed C-M diagrams. We estimate the age of NGC 2324 to be log t$~$8.8 by applying isochrone fitting and morphological age index method.
