  The dynamics of dwarf irregular (dIrr) galaxies are observed to be dominated
by dark matter (DM). Recently, the DM density distribution has been studied for
31 dIrrs. Their extended DM halo (Burket type profile) makes these objects good
candidates for DM searches. Located in Puebla (Mexico), the High Altitude Water
Cherenkov (HAWC) Observatory is an optimal in- strument to perform such DM
searches, because of its large sky coverage (8.4 sr per day). We analyzed a set
of two years of HAWC data and we found no significant DM signal from dIrr
galaxies. We present the upper limits for DM annihilation cross-section with
dIrr galaxies.
