Pepinia is a subgenus of plants in the family Bromeliaceae.

The name is for Pierre Denis Pépin, French member of the Imperial and Central Society of Agriculture (c.1802-1876).

[1] Pepinia was established as a genus in 1870 by Adolphe-Théodore Brongniart in a publication by Édouard André.

[2] Pepinia was reduced to a subgenus of Pitcairnia in 1881 by John Gilbert Baker,[3] but elevated again to a genus in 1988, largely on the basis of the morphology of its seeds.

[4] The use of morphological characters to differentiate Pepinia from Pitcairnia was rejected in 1999;[5] a view later confirmed by multiple molecular studies.
