Dagetichthys is a genus of soles. They are found in salt and brackish water in the East Atlantic and Eastern Indian Ocean, but D. lakdoensis is restricted to fresh water in Cameroon.

Taxonomy Dagetichthys was previously a monotypic genus which contained just D. lakdoensis. Synaptura was considered an incorrect designation by the ICZN and their species were added here.

Species Six species are recognized as valid: Dagetichthys albomaculatus (Kaup, 1858) Dagetichthys cadenati (Chabanaud, 1948) Dagetichthys commersonnii (Lacepède, 1802) Dagetichthys lakdoensis Stauch & Blanc, 1964 Dagetichthys lusitanicus (Brito Capello, 1868) Dagetichthys marginatus (Boulenger, 1900)
