'''IC 447''' is a [[reflection nebula]] located in the [[constellation]] [[Monoceros (constellation)|Monoceros]].<ref name=SkyLive/> It includes several massive B-type stars and forms one end of the Monoceros R1 star-forming filament, with [[IC 446]] at the opposite end.<ref name=Bhadari_et_al_2020/> IC 447 may have been formed by more massive members of the young [[open cluster]] [[Collinder 95]].<ref name=Lim_et_al_2022/>
