The present study offers a parasitological analysis of juvenile individuals of the green turtle (Chelonia mydas) found on the Brazilian coast between 2004 and 2011. Helminths were found in 90 out of 136 individuals (66.2%, CI = 57.7–74.0). In total, 29,411 helminths were collected, belonging to the families Brachycoeliidae, Cladorchiidae, Microscaphidiidae, Pronocephalidae, Rhytidodidae, and Spirorchiidae. Mean species richness was 4.74 (CI = 4.03–5.46), the mean intensity was 327 (CI = 223–489), and the mean abundance was 216 (CI = 146–339). This study also reports new geographical records for: Angiodictyum longum, Angiodictyum parallelum, Rameshwarotrema uterocrescens, Pyelosomum cochlear, Schizamphistomum scleroporum, Cymatocarpus solearis, and Neospirorchis sp. This is the first analysis of helminth composition in juveniles of green turtles
