Deltatheridiidae is an extinct family of basal metatherians that lived in the Cretaceous and were closely related to marsupials. Their fossils are restricted to Central Asia (Mongolia and Uzbekistan) and North America (United States - Oklahoma, Texas, Utah, Wyoming).
The family consist in six genera:[1][2][3]
- Atokatheridium Kielan-Jaworowska & Cifelli, 2001
- Deltatheridium Gregory & Simpson, 1926
- Deltatheroides Gregory & Simpson, 1926
- Oklatheridium Davis, Cifelli & Kielan-Jaworowska, 2008
- Nanocuris Fox, Scott & Bryant, 2007
- Sulestes Nessov, 1985
