A total of 16 species of intertidal brachyuran crabs were recorded from the three major estuaries (Punta Banda, False Bay-San Quintín and Laguna Manuela) of the west coast of the state of Baja California, Mexico. The species belong to 7 families: Cancridae (3), Grapsidae (2), Ocypodidae (2), Panopeidae (3), Pinnotheridae (4), Portunidae (1) and Varunidae (1). New distributional records include an extension of the northern limits of Cyrtoplax schmitti Rathbun, 1935, Panopeus purpureus Lockington, 1877, Goniopsis pulchra (Lockington, 1877), Uca princeps (Smith, 1870) and Pinnixa longipes (Lockington 1877).
