The Tsagaantsav Formation, Tsagantsab Formation or Tsagan-Tsab Formation (Russian: Tsagaantsav Svita) is an Early Cretaceous (Hauterivian to Barremian) geologic formation in Mongolia.^[1] Indeterminate sauropod and psittacosaurid remains have been recovered from the formation.^[2] Remains of the pterosaur Noripterus, which were originally given their own genus, "Phobetor" have also been recovered from the formation.^[3]^[4]

Graham et al. 2001 reported radiometric dates of 131 and 126 Ma from the formation.^[5]
