The restingas in the state of Rio de Janeiro are characterized by a high diversity of habitats and floristic wealth. The Jurubatiba Sandbank National Park (JSNP) stands out as the largest remaining restinga in Brazil, and has 10 different plant communities. This work aims to present the updated floristic list of Fabaceae at the JSNP, and also to analyze and discuss the distribution of species by the existing phytophysiognomy. 56 species and one variety, subordinate to 33 Fabaceae genera were registered in the JSNP, which is equivalent to about 36% of the species, and 51% of the genera mentioned for the restingas of Rio de Janeiro. The results indicate the importance of Fabaceae in the floristic composition of the JSNP, with representation in eight of the plant communities. The forest of sandy cord is the phytophysiognomy with the greatest wealth (24 species). The arboreal habit is the most frequent among the registered species, and only three species have a wide distribution in the PNRJ phytophysiognomies.
