The coat of arms of the municipality of Florianópolis was created by municipal law nº 1.408, of March 15, 1976, as suggested by the Commission, composed by professors Oswaldo Rodrigues Cabral, Vitor A. Peluso Jr. and Carlos Humberto P. Corrêa.
The symbol is composed of a Portuguese-style shield, cutting across the horizon, with a rising sun in gold on a blue background. At the bottom, three wavy silver pieces represent the sea.
The island of Santa Catarina is symbolized by a gold shield in the center of the shield, bordered in red and containing the Cross of the Order of Christ. This set represents the Azores and its people, inhabitants of the Island. On the shield, there is a golden mural crown, symbol of fortified cities such as Desterro.
The coat of arms rests on a blue stripe, with the word Florianópolis in the center, preceded by the date of 1726, the year of the foundation of the Municipality with Vila forums and installation of the first Chamber, followed by the date of 1823, the year of elevation to the category of City.
Flanking the coat of arms, on the right, is a representation of the pioneer Dias Velho, founder of Nossa Senhora do Desterro, the former name of Florianópolis. On the left is an officer of the Santa Catarina Island Line Infantry Regiment, also known as the Barriga Verde Regiment. The officer is dressed according to the Portuguese army uniform plan.
