Hepsetus is a genus of African fishes, the African pikes or African pike characins, in the order Characiformes. It is the sole genus in the family Hepsetidae. It was long believed that only a single widespread species existed, H. odoe, but studies in 2011–2013 have shown that this species is restricted to parts of West and Central Africa. The well-known species of southern Africa, including Kafue River, is Hepsetus cuvieri. These predatory fish reach up to 44 cm (17 in) in length.
A 2024 study found their closest relatives to be the newly-defined family Lepidarchidae, which they diverged from during the Late Cretaceous. The divergence of these two families appears to have been driven by the Trans-Saharan Seaway, which served as a marine barrier between western and eastern Africa at the time.
