Paraphrynus is a genus of whip spiders, also known as tailless whip scorpions (order Amblypygi), of the family Phrynidae. It is distributed from the southwestern United States to Central America, including several Caribbean islands. Most species are endemic to Mexico.

The genus was first described as Hemiphrynus by Reginald Pocock in 1902. Since there was already a beetle genus named Hemiphrynus, A. Moreno renamed the genus Paraphrynus in 1940. The genus was revised by Carolyn Mullinex in 1975.
