Using high-resolution data of the $^{12}$CO and $^{13}$CO (J=1-0) line emission from the Mopra Galactic Plane CO Survey in conjunction with neutral hydrogen observations from the Southern Galactic Plane Survey (SGPS), and mid-infrared Spitzer data, we have explored the large-scale environment of the supernova remnant (SNR) Kes 41. On the basis of these data we identified for the first time the parent cloud of Kes 41 in its whole extension and surveyed the HII regions, masers, and massive young stellar objects population in the cloud. The whole unveiled giant cloud, located at the kinematic distance of 12.0 $\pm$ 3.6 kpc, whose average total mass and size respectively are $\sim$10-30 $\times$ $10^5$ $\mathrm{M}_\odot$ and $\sim$$26^{\prime}$, also shines in $\gamma$-rays, as revealed by the Large Area Telescope onboard the Fermi satellite. We determined a high average proton density $\sim$500-1000 cm$^{-3}$ in the large molecular complex of which protons from the neutral atomic and ionised gases comprise only $\sim$15%.
