We present new $^{12}$CO($J$ = 1-0, 3-2), HI, and 1.4 GHz radio-continuum observations of the SNR N49 using Mopra, ASTE, ALMA, and ATCA. We have newly identified three HI clouds using ATCA with an angular resolution of ~20\": one associated with the SNR and the others located in front of the SNR. Both the CO and HI clouds in the velocity range from 280-291 km s$^{-1}$ are spatially correlated with both the soft X-rays (0.2-1.2 keV) and the hard X-rays (2.0-7.0 keV) of N49 on a ~10 pc scale.
