We present the catalogue of 60910 local stars brighter than Ks=8.2mag, which were assigned to be the most probable Red Clump candidates from Ks-band reduced proper motions. The catalogue is the result of analysis of combined Tycho-2 and 2MASS data selected in (J-Ks) interval from 0.5 to 0.8mag. It includes Tycho-2, Hipparcos and 2MASS numbers, equatorial coordinates J2000.0, proper motions and their standard errors, Tycho-2 B and V magnitudes, 2MASS J, H, Ks magnitudes, and Red Clump probabilities. All astrometric data were extracted from the Tycho-2 main catalogue; photometric data were extracted from the Tycho-2 and 2MASS catalogues. Red Clump probabilities were calculated by means of maximum-likelihood method based on Ks-band reduced proper motions. The catalogue provides data listed in order of right ascension increasing. About 85% of the sample stars are proved may be actual Red Clump giants as resulted from both Ks-band absolute magnitude analysis and the MK spectral classification.
