We present H$_\alpha$ photometry for a sample of 95 galaxies in HicksonCompact Groups obtained from observations of 31 groups. The Catalogue listsisophotal and adaptive aperture (Kron aperture) flux measurements for about 75%of the accordant galaxies inside the observed HCGs, 22 out of which are upperlimits. Non standard data reduction procedures have been used to obtain thecontinuum subtracted H$_\alpha$ images for each HCG of the target sample. Fluxcalibration has also been performed in order to obtain H$_\alpha$ luminositiesfor the whole sample. Both the data reduction and calibration procedures arecarefully described in this paper. The new data listed in this Catalogue are ofgreat importance in understanding the star formation rate inside HCG galaxiesand in giving new insights on its dependence on galaxy interactions.Comment: Accepted for publication in A&AS, 22 pages, including 23 figure
