Acacia argyrodendron, known colloquially as black gidyea or blackwood, is a species of Acacia native to Australia. Czech botanist Karel Domin described this species in 1926 and it still bears its original name. Domin reported collecting the type specimen from somewhere between Camooweal and Burketown in northwestern Queensland, though it is more likely to have been northeast of Aramac. Acacia argyrodendron is a tree, reaching 8 to 25 m (26 to 82 ft) high, and has dark grey to black bark.
