Acacia linifolia, known colloquially as white wattle, or flax wattle, is a species of Acacia native to eastern Australia.
Acacia linifolia was first described in 1800 by Étienne Pierre Ventenat as Mimosa linifolia. In 1806 Carl Ludwig Willdenow redescribed it as belonging to the genus, Acacia, and it became Acacia linifolia.
