Diomedea sanfordi breaks into Diomedea, referring to Diomedes, whose companions turned to birds, and sanfordi, in honor of Leonard Cutler Sanford (1868–1950), ornithologist, and trustee of the American Museum of Natural History.

Albatrosses belong to the family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns, although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that are stored in the proventriculus. This is used against predators as well as an energy rich food source for chicks and adults during their long flights. The northern royal albatross was first described as Diomedea sanfordi by Robert Cushman Murphy, in 1917, based on a specimen from the Chatham Islands. weighs , and has a wingspan from The juvenile has a white head, neck, upper mantle, rump, and underparts. There is dark speckling on the crown and rump. Its lower mantle and back are white with more black speckling than the crown, and it has dark black brown upper wings with white flecks on its coverts. Its tail is white with a black brown tip, as are its underwings. There is a black band behind the leading edge of its wings between the carpal joint and the tip. As they age, their head, back, rump, tail, and scapular region whiten. All ages have a pink bill with a black cutting edge on the upper mandible, along with pale pink legs. Counting of individual birds has been made possible using 30 cm resolution imagery from the WorldView 3 satellite. Thanks to the efforts of L. E. Richdale, the colony on Taiaroa Head was protected by 1950. 1972 saw the first formal guided viewing of their breeding area, since 2001 more than 100,000 people visit the Royal Albatross Centre annually to watch this species.
