Archaeospheniscus wimani is an extinct species of penguin. It was the smallest species of the genus Archaeospheniscus, being approximately 75-85 cm high, or about the size of a gentoo penguin. It is also the oldest known species of its genus, as its remains were found in Middle or Late Eocene strata (34-50 MYA) of the La Meseta Formation on Seymour Island, Antarctica. It is known from a fair number of bones.

The species' binomen honors Carl Wiman, an early 20th-century researcher who laid the groundwork for the classification of the prehistoric penguins.
