A ventilated umbrella includes a support frame forming a fully expand surface when it is fully expanded, a first canopy secured on the inner area of the fully expanded surface of the support frame and having an outer edge, and a band-shaped second canopy secured on the outer area of the fully expanded surface of the support frame and slightly overlapped by the first canopy. The second canopy has an inner edge located under the outer edge of the first canopy, and multiple extensions strips each extending inward from the inner edge of the second canopy, and each secured to the support frame. In such a manner, the gap between the outer edge of the first canopy and the inner edge of the second canopy is enlarged by stretching each of the extension strips, thereby enhancing the ventilating effect.
