The following list is about Cockroaches recorded in Sri Lanka.

Cockroach

Phylum: Arthropoda
Class: Insecta
Order: Blattodea

Cockroaches are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. About four species are well known as pests. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of Hemiptera; they have chewing mouthparts and are likely among the most primitive of living neopteran insects. They are common and hardy insects, and can tolerate a wide range of environments from Arctic cold to tropical heat. Tropical cockroaches are often much bigger than temperate species, and, contrary to popular opinion, extinct cockroach relatives and 'roachoids' such as the Carboniferous Archimylacris and the Permian Apthoroblattina were not as large as the biggest modern species.

Cockroaches are members of the order Blattodea, which includes the termites, a group of insects once thought to be separate from cockroaches. Currently, there are 4,600 species described and over 460 genera worldwide.[1][2]

The following list provide the cockroaches currently identified in Sri Lanka. An exclusive update and taxonomic research on cockroaches in Sri Lanka has been not under taken so far by the scientific community.[3] With records and few earlier studies, they have found that 66 species of cockroaches can be found from Sri Lanka,[4] belongs to 6 families and 31 genera.[5][6]

Endemic species are denoted as E.
