Gazania rigens is a species of flowering plant native to southern Africa. It is naturalised elsewhere and is widely cultivated as an ornamental garden plant. In New Zealand, the species has become naturalised in some coastal dunes.

It is a spreading, low-growing, half-hardy perennial, growing to 50 cm tall and wide, with blue-grey foliage that is glabrous above and white underneath.
The daisy-like composite flowers have rays that are a golden yellow to orange with black spot (eye) near the base of each floret. The heads are large when fully expanded 40–80 mm in diameter; involucre cup-shaped, 10–15 mm long (high). Flowering occurs throughout the summer.
