Satyrex is a genus of tarantulas in the family Theraphosidae.
The genus is partially characterised by possessing the longest male palps known in tarantulas, possibly functioning in cannibalism avoidance during mating.
Satyrex is distributed across the Arabian Peninsula and the Horn of Africa. The genus occurs in Saudi Arabia, Yemen, Oman, and Somalia.
The genus name is a combination of Satyr, a part-man, part beast entity from Greek mythology known for his exceptionally large genitals, and the Latin rēx, meaning king.
As of October 2025[update], this genus includes five species:
