The coastal lagoons are system in which many factors interact in complex w ys. The objective of this study is to establish a caracterization of the Guerrero coas­tal lagoons in four variable groups: 1) Morphometrics; among others, area, total volume, perimeter, relative depth, middle depth, max, depth and development of the coastal line and volume among other variables. 2) Hidroclimate: rainfall, mean environmental temperature, weather, basin area and fluvial discharge. 3) Physico-Chemical: salinity, temperature and dissolved oxigen. 4) Biological: presence of pisces, crustacea and mollusca. To establish any relationship between the lagoon for each variable group, the data were processes by means of a multivariate analysis (Cluster). The first variable group showed two affinity blocks; Mitla and Tres Palos on the first and Potosi, Nuxco and Coyuca on the other. Chautengo displays a low affinity arrangement with Mitla, Tres Palos on one block and Potosi, Nuxco, Salinas de Apozahualco and Chautengo on the other. This type of analysis permit regionalized the lagoons of the Coastal Plain of Guerrero for a better understanding and classification.
