Caridina tetrazona is a species of freshwater shrimp native to the Wanshan islands in Guangdong Province, southern China.

[1] It was described from specimens collected on Dawanshan Island, where it is found alongside Caridina serrata.

The name 'tetrazona' refers to the four banded color patter found in this species.

A phylogenetic analysis conducted by Chen, Chen, and Guo (2020) found Caridina Tetrazona to be sister to C. serrata, with both of these species closely related to C. trifasciata.
