Iriss is a variant of Iris, from Greek, meaning rainbow and linked to the flower and goddess Iris.
Iriss is a variant spelling of Iris, from Greek, meaning rainbow and linked to the flower and the goddess Iris. That gives the name a double identity: mythological messenger and botanical image.
The extra s creates a slightly stylized look, but the classical associations remain unmistakable. The name has a natural brightness to it, and that suits both its rainbow meaning and its floral connection. Iris has long felt fresh and elegant, and Iriss preserves that effect while making the spelling feel more individualized.
It is rare enough to stand out, but familiar enough to be immediately legible. The result is a name that feels airy, colorful, and lightly mythic, with a modern twist on an old favorite.
