Between September 2006 and June 2007 the assembly structure of chitons was characterized in seven stations of the rocky coast of Cordoba, Colombia. In samples was used a string defining an area of 25 m2 with three replications randomly arranged at each station at depths equal to or less than 1 m. Were collected 524 specimens of five species of the families Acanthochitonidae, Chitonidae, and Ischnochitonidae. The study shows that three clusters of stations define the assembly structure of chitons in Cordoba. The first one formed by station 1 and 3 of San Antero, characterized by the presence of Acanthopleura granulata and Chiton tuberculatus. The second one formed by stations 3, 4, 5 and 6 of Monitos and Puerto Escondido, gathered A. granulata, C. marmoratus, and C. tuberculatus while the third cluster was associated with station 7 of Los Cordobas, showing C. marmoratus as the dominant specie. It was included two new records for the Caribbean Cordoba; Acanthochitona spiculosa and Ischnochiton striolatus, which were collected from rocky shores of San Antero platform, Monitos, and Puerto Escondido.
