Colquhounia is a genus of six species of evergreen or semi-evergreen shrubs or subshrubs in the family Lamiaceae, native to the eastern Himalaya and southwestern China south to Thailand and Vietnam.

They are shrubs growing to 1-3 m tall, rarely to 4 m. The aromatic leaves are 3-12 cm long and 1-6 cm broad, finely toothed and borne in opposite pairs on the square stems. The flowers are tubular, 2-lipped, and carried on terminal spikes.

Pronunciation of the name might present problems to non-Scots; the surname of the botanical collector Sir Robert Colquhoun was pronounced 'co-hoon', if present-day Scottish usage is a guide.
