Oryzias sarasinorum, the Sarasins minnow or Sarasins buntingi, is a species of ricefish in the Adrianichthyidae. It is endemic to Lake Lindu in Lore Lindu National Park, Sulawesi, Indonesia.

Although the IUCN state that the population of this fish is stabled it is threatened by introduced non native fish, common carp, Mozambique tilapia and walking catfish; and a decline in water quality caused by increased agriculture in the lake's catchment which is causing a decline in water quality, it is therefore assessed as Critically Endangered.
