Siksika ottae is an extinct species of petalodont (a type of prehistoric cartilaginous fish), which lived during the Upper Mississippian. It has been discovered at the well known Carboniferous-aged Bear Gulch Limestone (Montana, United States ). It is known primarily from fossil teeth, but also from partial neurocranium and mandibles which hint at a close relationship to coeval petalodontiforms such as Janassa and Netsepoye. Dentition is generally heterodont. Siksika translates to Blackfoot, being named after the Siksika Nation.
