Impatiens ×pacifica Zika (Balsaminaceae), a natural spontaneous hybrid, is described from western North America, in coastal Oregon and Washington. A key is provided, and the hybrid is compared with its parents, the common introduction Impatiens capensis Meerburgh and the uncommon native I. ecalcarata Blankinship. Hybrid flowers are intermediate in markings and morphology between those of the parents. Impatiens ×pacifica differs from I. ecalcarata in its spotted corolla and from I. capensis in its spurless flowers.
