Brabantio (sometimes called Brabanzio) is a character in William Shakespeare's Othello (c. 1601–1604).

Brabantio makes his first appearance in 1.1 when Iago and Roderigo rouse him with the news that Desdemona has eloped.

In 1.2, Brabantio is led to the Sagittary, where the newlyweds are found and there accuses Othello of using magic to bewitch his daughter.

When Desdemona arrives, she tells her father that she respects him only because they are related, and that Othello is whom she truly loves.

Brabantio grudgingly accepts what she says, but not without complaining to the senators in an attempt at having Othello stripped of his title; when this is unsuccessful, he disowns his daughter.
