Castilleja kerryana is a species of flowering plant in the broomrape family. It was formally described in 2013 and so far it is known only from a small population in the state of Montana, in the Northwestern United States. The first collection of this plant was tentatively identified as a specimen of Castilleja crista-galli, and it is also similar to C. fraterna and C. pulchella. It differs from the latter two in its color and in the shape of its stem and flower corolla.
