Speyeria hesperis, the northwestern fritillary, is a butterfly of the family Nymphalidae. It is found in the northwestern United States and western Canada, as far east as Manitoba and the Dakotas.[1][2]

With a wingspan of between 45–58 millimetres (1.8–2.3 in), this fritillary is relatively small. It has bright orange uppersides (yellow in females) and thinner black markings than most fritillaries.[1]
