In this paper, we expose pythagorean fuzzy sets in BCK-algebras. Also we define pythagorean fuzzy subalgebra, pythagorean fuzzy ideal in BCK-algebra and investigate some properties of these ideals. Some interesting examples are given. Homomorphism of pythagorean fuzzy set in BCK-algebras are introduce. Moreover we combine the pythagorean fuzzy set and rough sets in BCK-algebras. The concept of rough pythagorean fuzzy ideals in BCK-algebras are introduce.
