Acacia tumida, known colloquially as pindan wattle, spear wattle or wongai, is a species of Acacia native to northern and western Australia.

The openly branched spreading tree or shrub typically grows to a height of 5 to 15 metres (16 to 49 ft) with a well developed canopy. It has hard grey glossy bark that is occasionally fissured with pruinose orange to yellow branchlets. It has falcate to subfalcate glaucous green phyllodes that are 6 to 25 centimetres (2 to 10 in) long and 0.7 to 6 cm (0.3 to 2.4 in) wide.

It produces between April and October and produces yellowinflorescences usually Inflorescences usually racemose or axillary or terminal panicles 20 cm (7.9 in) long. These eventually develop into narrow oblong woody glabrous seed pods that are 3 to 12 cm (1.2 to 4.7 in) in length containing glossy black seeds.
