We prove the multidimensional stability of planar traveling waves for scalar nonlocal Allen-Cahn equations using semigroup estimates. We show that if the traveling wave is spectrally stable in one space dimension, then it is stable in n-space dimension, n >= 2, with perturbations of the traveling wave decaying like t(-(n-1)/4) as t -> +infinity in H-k(R-n) for k >= [n+1/2].
