For the free group F r on r> 1 generators (respectively, the free product G 1⁎ G 2 of two nontrivial finite groups G 1 and G 2), we obtain the asymptotic for the number of conjugacy classes of commutators in F r (respectively, G 1⁎ G 2) with a given word length in a fixed set of free generators (respectively, the set of generators given by the nontrivial elements of G 1 and G 2). Our result is proven by using the classification of commutators in free groups and in free products by Wicks, and builds on the works of Rivin and Sharp, who asymptotically counted the conjugacy classes of commutator-subgroup elements in F r with a given word length.
