Sir Robert Colquhoun of Luss, Bart (died 1838) served in the British Indian Army. In 1815 in present-day Almora, holding the rank of lieutenant, he organized the Kemaoon Battalion, predecessor of the 3rd Gorkha Rifles, to fight in what became known as the Gurkha War.

Colquhoun was a plant collector and early patron of the Calcutta Botanical Gardens. The evergreen genus Colquhounia was named in his honor.
