Lophelia　pertusa　plays　an　important　role　as　a　major　contributor　to　many　cold-water　coral　reefs,　supporting　a　high　diversity　of　associated　benthic　and　benthopelagic　species.　Due　to　the　high　sensitivity　of　L.　pertusa　to　human　activity,　it　has　been　classified　as　indicator　species　for　Vulnerable　Marine　Ecosystems.　However,　the　global　spatial　distribution　of　L.　pertusa　is　far　from　well　known.　In　this　study,　a　database　of　L.　pertusa　presence　data　was　compiled　derived　from　the　large　number　of　L.　pertusa　occurrence　records　appearing　in　recent　years.　In　conjunction　with　data　layers　covering　a　range　of　environmental　drivers,　habitat　suitability　for　L.　pertusa　was　predicted　using　the　Random　Forest　approach.　Suitable　habitat　for　L.　pertusa　was　predicted　to　occur　primarily　on　continental　margins,　with　the　most　suitable　habitat　likely　to　occur　in　the　North　East　Atlantic　and　South　Eastern　United　States　of　America.　Aragonite　saturation　state,　temperature　and　salinity　were　identified　as　the　most　important　contributors　to　the　habitat　suitability　model.　Given　the　high　vulnerability　of　reef-forming　cold-water　corals　to　anthropogenic　impacts,　habitat　suitability　models　are　critical　in　developing　worldwide　conservation　and　management　strategies　for　biodiverse　and　biomass　rich　cold-water　coral　ecosystems.
