Cambarellus chihuahuae, the Chihuahua dwarf crayfish,[1][3] is a small, freshwater crayfish endemic to Chihuahua in Mexico.

It is known from only one spring, Ojo de Carbonera, 4.3 km (2.7 mi) south of Ejido Rancho Nuevo.

[2] It shares this habitat with the co-endemic Cyprinodon fontinalis and Cyprinella bocagrande Regular surveys are carried out of the spring site to observe the three endangered species, and when a 2009 survey found most springs dry, and the only one with water to contain no crayfish, it was considered as being extinct in 2010.

[2] Further surveys, looking for fish, led to its rediscovery in September 2012.
