Hybridization between members of the genus <jats:italic>Crocodylus<\/jats:italic> has been known to occur in captivity and in some wild populations. We tested for hybridization among wild populations of American crocodile (<jats:italic>C. acutus<\/jats:italic>) and Morelet's crocodile (<jats:italic>C. moreletii<\/jats:italic>) in the Yucatan Peninsula by comparing Bayesian assignment tests, based on microsatellite data, to mitochondrial and morphological assignments. Skin clips from 83 individuals were taken for genetic identification, and a total of 32 individuals (38.6%) exhibited some evidence of hybridization by combined morphological, mitochondrial and microsatellite analyses. The majority of hybrids were classified as F<jats:sub>2<\/jats:sub> hybrids and backcrosses to <jats:italic>C. moreletii<\/jats:italic>. Most of the introgression occurs in two national biosphere reserves located on the northern and eastern coasts of the Yucatan Peninsula. Preliminary tests did not find a significant decrease in hybridity across three life stages, thus far indicating a low level of selection against hybrids. Model\u2010based analyses on multilocus genotypes of pure individuals returned little geographic partitioning in both <jats:italic>C. acutus<\/jats:italic> and <jats:italic>C. moreletii. J. Exp.
