The specific epithet is derived from the Greek 'pedinos', pertaining to the blade of an oar, since the phyllodes, particularly the large juvenile/intermediate phyllodes, of this species are often more or less paddle-shaped. Acacia pedina is closely related to the more widespread Acacia pycnantha, which generally has longer, falcate phyllodes and larger flower heads. See P.G. Kodela & T.M. Tame, Telopea 8(3): 305–309 (1999) for more information.
