Plantago stauntonii is a species of flowering plant in the family Plantaginaceae that is endemic to Île Amsterdam and Île Saint-Paul in the French southern territories.

It was first described by Heinrich Wilhelm Reichardt in 1871 based on specimens collected by Anton Jelinek in Île Saint-Paul and George Staunton on Île Amsterdam.

[2][1] The specific epithet honors Sir George Leonard Staunton, 1st Baronet (1737 – 1801), an Anglo-Irish botanist who visited Île Amsterdam in February 1793,[1] when he collected specimens of this species.

[3] At the time of its description, Reichardt likened P. stauntonii to P. aucklandica from the subantarctic Auckland Islands, New Zealand, and other subantarctic and South American species.
