Glikmanius is an extinct genus of ctenacanth cartilaginous fish which lived in the Carboniferous and Permian of North America and Russia. Skeletal remains attributed to the genus are known from Nebraska, USA. Glikmanius is named in honour of the Russian palaeontologist, Dr. Leonid Glikman, who studied the genus and was "the first to propose its ctenacanthiform affinity".
