A single specimen of Carangoides oblongus (133.8 mm SL) belonging to the family Carangidae was firstly collected by a set net from the coastal waters of Jeju Island, Korea. This species resembles Carangoides dinema, but the former is morphologically distinguishable from the latter by lateral line being shorter than straight part, the number of lateral line scutes (37~45 in C. oblongus vs. 20~30 in C. dinema), second dorsal fin rays (20~22 vs. 17~19), and anal fin rays (18~19 vs. 15~17). We newly add this species to the Korean fish fauna and propose its new Korean name "Chae-jjik-yu-jeon-gaeng-i".
