Quoya oldfieldii, commonly known as Oldfield's foxglove,[2] is a flowering plant in the mint family Lamiaceae and is endemic to the south-west of Western Australia.

The five petals are joined to form a tube 18–23 mm (0.7–0.9 in) long and which is pale pink with purple dots inside and has five lobes on its end.

Flowering occurs mainly from May to October or November and is followed by oval fruit, 3–4 mm (0.12–0.16 in) long and densely hairy with the sepals remaining attached.

Flowering occurs mainly from June to November or December and is followed by hairy, oval or almost spherical fruit with the sepals attached.

The description was published in Fragmenta phytographiae Australiae from a specimen collected by Augustus Oldfield near the Murchison River.
