Dendrobium veillonii is an endemic lithophyte orchid of New Caledonia restricted to the north west of Grande Terre. It is known from two subpopulations: Tiébaghi and Montagne Poum. The species occurs in forest egdes and humid forest's slopes on ultramafic substrates at an altitude range of 200 and 365 m asl. The main threats are the impact bushfires and mining activties. Its area of occurrence (EOO) and area of occupancy (AOO) are estimated to be 27 and 16 km² while the number of locations is estimated to be two. Therefore, Dendrobium veillonii is assessed as Endangered (EN) B1ab(i,ii,iii,v)+2ab(i,ii,iii,v) with an estimated decline of the concerned criteria.
