Impatiens namchabarwensis (blue diamond impatiens) is a 40–50 cm tall plant, native to the Himalaya.

It is an annual plant, although it may live for several years in mild climates that do not freeze in winter.

This new species was discovered in the Namcha Barwa canyon in Tibet in the summer of 2003 by Yuan Yong-Ming and Ge Xue-Jun.

Flowers are bright ultramarine blue, with small white markings at center and yellow in throat.

It has explosive seedpods, like the other species of the family Balsaminaceae.
