Abstract: In this article, the concept of lacunary ideal convergent double sequences of fuzzy numbers have been introduced. Also the relation between lacunary ideal convergent and lacunary ideal Cauchy double sequences of fuzzy numbers have been established. Furthermore, the notions of lacunary ideal limit point and lacunary ideal cluster points have been introduced and find the relation between these two notions.
