The primary goal of this study was to determine the extent of population differentiation among alligators from four Florida lakes using eight microsatellite loci and compare the results to additional sites located at varying distances from them. Analyses of population structure revealed little differentiation (F<jats:sub>ST<\/jats:sub>=0.039; Rho=0.012) among the four Florida lakes, Apopka, Griffin, Orange and Woodruff, which are all located in the St. John&amp;&amp;apos;s River watershed in north\u2010central Florida. Further, there was little differentiation among these samples and samples collected from the Everglades National Park (F<jats:sub>ST<\/jats:sub>=0.044; Rho=0.009) and south Georgia (F<jats:sub>ST<\/jats:sub>=0.045; Rho=0.032). Therefore, these six samples were pooled together as a \u201cFL\/sGA group.\u201d Similarly, samples collected in the western extent of the range, Anahuac National Wildlife Refuge in Texas and Salvador Wildlife Management Area, Marsh Island Wildlife Refuge and Rockefeller Wildlife Refuge in Louisiana, also lacked population structure (F<jats:sub>ST<\/jats:sub>=0.024; R<jats:sub>ST<\/jats:sub>=0.040). These four populations were pooled into the \u201cTX\/LA group.\u201d Comparisons of these two groups with samples taken from the Santee Coastal Reserve in South Carolina and Mobile, Alabama yielded three to four times more differentiation among groups (F<jats:sub>ST<\/jats:sub>=0.131; Rho=0.187). These and other analyses support the hypothesis of an east\u2010west phylogeographic split in American alligator populations and are consistent with studies of many freshwater fish and aquatic and terrestrial turtles distributed throughout this same geographic region. <jats:italic>J.
