Acacia burkittii is a species of wattle endemic to Western Australia and is a perennial shrub in the family Fabaceae; common names for it include Burkitt's wattle, fine leaf jam, gunderbluey, pin bush and sandhill wattle. It is common in southwestern regions of Western Australia and extends east over towards South Australia. It has also been introduced into India. Previously this species was referred to as Acacia acuminata subsp. burkittii, but is now considered to be a separate species. Grows in mallee, eucalypt and mulga woodland or shrubland, often on sandhills.
