Don (Spanish: [ˈdon], Italian: [ˈdɔn], Portuguese: Dom [ˈdõ]) from Latin dominus, is an honorific title used in Iberia and Italy. The female equivalent is Doña (Spanish: [ˈdoɲa]), Donna (Italian: [ˈdɔnna]), and Dona (Portuguese: [ˈdonɐ]), abbreviated "Dª" or simply "D."

Although originally a title reserved for royalty, select nobles, and church hierarchs, it is now often used as a mark of esteem for a person of personal, social or official distinction, such as a community leader of long standing, a person of significant wealth, or a noble, but may also be used ironically. As a style, rather than a title or rank, it is used with, and not instead of, a person's name.

Syntactically, it is used in much the same way (although for a broader group of persons) as "Sir" and "Dame" are used in English when speaking of or to a person who has been knighted, e.g. "Don Firstname" or "Doña Firstname Lastname". Unlike "The Honourable" in English, Don may be used when speaking directly to a person, and unlike "Mister" it must be used with a given name. For example, "Don Diego de la Vega," or (abbreviating "señor") "Sr. Don Diego de la Vega," or simply "Don Diego" (the secret identity of Zorro) are typical forms. But a form like "Don de la Vega," is not correct. "Sr. Diego" is not correct either, even if it is becoming widespread in certain environments (e.g.: supermarkets' megaphone systems) where people try to sound formal despite their lack of awareness regarding style.^{[original research?]}
