Plantago aucklandica is a species of flowering plant in the family Plantaginaceae that is endemic to the subantarctic Auckland Islands, New Zealand.

This species in considered to be At Risk - Naturally Uncommon, as it is an island endemic with a restricted range.

[5] It was first described by Joseph Dalton Hooker in 1844, from specimens he had collected in the Auckland Islands "on the mountain ridges at an altitude of 1000-1200 feet, in a peaty soil" while serving on the Ross expedition in the Antarctic.

[4] The lectotype specimen was designated by Heidi Meudt, was collected by Joseph Hooker in November 1840 "in marshy places at top of the hill at back of Rendezvous Harbour, Lord Auckland Island," and is lodged at the Kew Herbarium (lectotype K000438784 and isolectotye K000438785 are on the same sheet).

[9] Plantago aucklandica plants are rosettes with a primary root up to 2.5 cm thick, with up to 13 narrowly angular-ovate or narrowly obovate leaves, and with long (up to 4 cm long), rust-coloured, obvious leaf axillary hairs in the basal rosette.

[4][5][10] It also occurs on ridge tops of Disappointment Island with Acaena minor var.

[13] In those studies, Plantago aucklandica was strongly supported as being closely related to the mainland New Zealand species P. obconica, P. novae-zelandiae and P.
