Hastimima is a genus of Brazilian eurypterid, a group of extinct marine arthropods. Fossils of Hastimima have been discovered in Permian coal deposits of the Rio Bonito Formation, in Santa Catarina. When they were originally described, the remains were identified as fossil plants of unknown affinity (incertae sedis) and named Hastimima whitei, only later being properly identified as eurypterids. Other specimens were reported from South Africa and Arizona, USA. However, these remains have been deemed as either nomen dubium or too undiagnostic for classification.

This genus is notable for being one of the few eurypterids discovered in the Southern Hemisphere.
