The flag of Umbria is one of the official symbols of the region of Umbria, Italy. The current flag was officially adopted on 18 March 2004, although the emblem and gonfalon had been in use since the 1970s. The Regional Law of 18 May 2004 officially confirmed the flag and added the words Regione Umbria ("Umbria Region") in red, centered in the bottom fifth of the flag, but in common usage, the words are omitted.
The flag of Umbria is inspired by a banner designed by architects Gino and Alberto Anselmi, winners of a 1971 competition, who described the symbolism:
We proposed [...] that the emblem and gonfalon would become signs of that territory, and thus would reflect the spirit, the tensions, the atmosphere, the colors of those places that still live on in deep medieval values.
The symbol in the flag's center represents the three candles of the Festa dei Ceri, which occurs annually on May 15 in Gubbio, Perugia, in honor of Saint Ubaldo Baldassini.
The coat of arms and flag of the region are officially defined as such:
The Coat of Arms of the Region consists of geometric elements depicting in graphic synthesis the three candles of Gubbio, red, bordered by white stripes, on a silver field rectangular in shape, as shown in the sketch attached, which forms an integral part of this Law ... the Flag of the Region consists of a cloth of rectangular shape, the same color as the gonfalon, with the coat of arms as referred to in Article 2 in the center, of dimensions equal to three-fifths of the height of the Flag itself, with the inscription "Umbria Region" in red in the bottom fifth.
