88 ostracode species have been found in the Upper Paleozoic Harper Ranch beds of south-central British Columbia, Canada. They occur with three different conodont associations that are dated as Early Carboniferous (Late Visean-Early Namurian) and Early Permian (Late Sakmarian, and Early Artinskian). The composition of the oldest ostracode fauna suggests a younger, Late Carboniferous/Sakmarian age for that fauna, which suggests some stratigraphic admixture has occurred. The ostracodes are the first described from the region, and the Permian ostracodes are the first described from Canada. Two genera are new: Valentinia n. gen. and Victoria n. gen.; 7 species are new: Valentinia harperensis n. sp., Valentinia vermiformis n. sp., Valentinia dercourti n. sp., Victoria hemicircularis n. sp., Victoria pinantonensis n. sp., Victoria postpleta n. sp., and Pseudobeyrichiopsis gerryi n. sp.; 17 species are firmly determined, 31 are compared to previously described material, and 40 species are in open nomenclature. Paleoecologically, the Carboniferous fauna of Pinanton Lake has deep water features, whereas Early Permian faunas are shallower; the Late Sakmarian assemblage is indicative of the shallowest water
