A new and distinct cultivar of geranium plant named `Fisnifire` particularly characterized by the combined features of brilliant, orange-red, single-type flowers, large inflorescences on, dark red peduncles; robust, dark-green foliage with strong zonation; initially fairly compact, but later medium to tall and well-branched plant habit, about medium spring flowering response; good weather resistance and well suited as a robust plant for landscaping.
