Resumo: 	The knowledge of the diameter structure of a forest is very important for the characterization of their stage of development and decision-making on forest management. Thus, this study aimed to identify this structure and the fitting evaluation of the probability density function (FDP) to the diameter frequency distribution of tree individuals in Iguaçu National Park (PNI) in three measurement periods (2011, 2013 and 2015). The data used came from a network of permanent plots, with 21 plots (20 x 100 m) totaling a sample area of 42.000 m², distributed along the altitudinal gradient on the PNI, in which all trees with DBH equal to or greater than 5 cm were measured. To evaluate the diameter distribution of the PNI it was adjusted the probability density functions most used in forestry: Normal, Lognormal, Beta, Gama, Weibull 3p and Johnson SB. For all measurement periods, the observed diameter distribution was “J-inverted” format. Fitting was evaluated by Kolmogorov-Smirnov’s test, which indicated that the Weibull 3p and Johnson SB with fitting in all tested periods, but results were better for the FDP Weibull 3p.
