Cassio

Cassio is a masculine given name of Latin origin, commonly used in Italian and Portuguese-speaking contexts. In Portuguese, the form Cássio is widespread, while other languages may render the name without the accent. The name derives from the Latin name Cassius, and in modern usage it appears primarily as a first name.

In literature and popular culture, Cassio is notably the name of a character in William Shakespeare’s Othello. Cassio serves as Othello’s loyal lieutenant, and his promotion and subsequent mistreatment by Iago drive much of the play’s action and its themes of trust, reputation, and manipulation.

Notable real-world bearers include Cássio, a Brazilian football goalkeeper often referred to simply as Cássio, who has been associated with the club Corinthians. The name is used across various Portuguese-speaking countries and can appear in other contexts as well, though it remains most recognizable in its given-name form.

Cassio is primarily encountered as a first name rather than a surname. Variants and related names include Cassius and Casio, and the form Cássio is the common Portuguese spelling.
