  We present H$_\alpha$ photometry for a sample of 95 galaxies in Hickson
Compact Groups obtained from observations of 31 groups. The Catalogue lists
isophotal and adaptive aperture (Kron aperture) flux measurements for about 75%
of the accordant galaxies inside the observed HCGs, 22 out of which are upper
limits. Non standard data reduction procedures have been used to obtain the
continuum subtracted H$_\alpha$ images for each HCG of the target sample. Flux
calibration has also been performed in order to obtain H$_\alpha$ luminosities
for the whole sample. Both the data reduction and calibration procedures are
carefully described in this paper. The new data listed in this Catalogue are of
great importance in understanding the star formation rate inside HCG galaxies
and in giving new insights on its dependence on galaxy interactions.
