In this work, we investigate the $\\Xi_{c}\\to\\Xi$ form factors in QCD sum rules. To this end, the two-point correlation functions of $\\Xi_{c}$ and $\\Xi$, and the three-point correlation functions of $\\Xi_{c}\\to\\Xi$ are calculated. At the QCD level, contributions from up to dimension-6 four-quark operators are considered, and the leading order results of the Wilson coefficients are obtained.
