Xanthorrhoea concava is a species of grasstree native to New South Wales, Australia.
X. concava has no discernible trunk, though it branches below ground and may have multiple crowns. The greyish to bluish-green leaves are about 3–6 mm (0.12–0.24 in) wide and 1.5–2 mm (0.059–0.079 in) thick. The scape is 0.5–2 m (1 ft 8 in – 6 ft 7 in) long and 1.5–3 cm (0.59–1.18 in) in diameter. The flower spike is half as long as the scape, 50–90 cm (20–35 in) long and 1.5–3 cm (0.59–1.18 in) in diameter.
This grasstree occurs in south-eastern New South Wales, from the Sydney region southwards to Eden, often on seasonally waterlogged sites.
