Pseudalsophis is a genus of snakes in the family Colubridae. The genus is endemic to South America.

Species in the genus Pseudalsophis are found in Ecuador (particularly the Galápagos) and Peru.

Seven species are recognized as being valid.

Pseudalsophis biserialis (Günther, 1860) – Galápagos racer, Floreana snake, Española snake, San Cristóbal snake

Pseudalsophis dorsalis (Steindachner, 1876) – Galápagos snake, Fernandina snake, Isabela snake

Pseudalsophis elegans (Tschudi, 1845)

Pseudalsophis hoodensis (Van Denburgh, 1912) – Hood Island snake

Pseudalsophis occidentalis (Van Denburgh, 1912)

Pseudalsophis slevini (Van Denburgh, 1912) – banded Galápagos snake, Slevin's snake,

Pseudalsophis steindachneri (Van Denburgh, 1912) – striped Galápagos snake, Steindachner's snake

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Pseudalsophis.

The specific names, slevini and steidachneri, are in honor of American herpetologist Joseph Richard Slevin and Austrian herpetologist Franz Steindachner, respectively.
