Abstract. Kac-Moody algebras is one of the modern fields of Mathematical research which has got interesting connections and applications to other fields of Mathematics and Mathematical Physics. On the other hand fuzzy theory has been finding deep rooted applications in all walks of life. In this paper, we define fuzzy sets on the Cartesian product of the simple roots of some of the affine type of Kac-Moody algebras. The fundamental fuzzy properties like normality, convexity and cardinality are studied for these affine Kac-Moody algebras. The $\alpha$-level, strong $\alpha$-level sets and $\alpha$-cut decomposition for these fuzzy sets, associated with the affine Kac-Moody algebras are computed.
