Pachygrapsus crassipes, the striped shore crab or lined shore crab, is a small crab found on both rocky and hard-mud soft seashores of the northeastern and northwestern Pacific Ocean. In North America, this species occurs from central Oregon, south through California to near Ensenada, Baja California, Mexico.

Pachygrapsus crassipes is a grapsid crab native to tidepools and mudflats of the Pacific Coast. Also known as the Striped Shore Crab or Lined Shore Crab, the crab is often seen scraping algae off of rocks during low tide. During high tide, the crab finds shelter between crevices and rocks.
