Colquhounia is a genus of about six species of evergreen or semi-evergreen shrubs or subshrubs in the family Lamiaceae, first described in 1822.

They are native to the Himalaya and southwestern China south to Peninsular Malaysia.

[1][2] They are shrubs growing to 1 to 3 metres (3 ft 3 in to 9 ft 10 in) tall, rarely to 4 metres (13 ft).

The aromatic leaves are to 3 to 12 centimetres (1.2 to 4.7 in) long and 1 to 6 centimetres (0.39 to 2.36 in), finely toothed and borne in opposite pairs on the square stems.

The flowers are tubular, two-lipped, and carried on terminal spikes.
