Hispanophone refers to anything related to the Spanish language.

In a cultural, rather than merely linguistic sense, the notion of "Hispanophone" goes further than the above definition. The Hispanic culture is the legacy of the vast and prolonged Spanish Empire, and so the term can refer to people whose cultural background is primarily associated with Spain, regardless of racial or geographical differences. The whole sense of identity of the Hispanic population and the Hispanophones is sometimes referred by the term Hispanidad (Hispanicity).

When used in terms to refer to speakers of the Spanish language and the Spanish-speaking world, the Hispanosphere encompasses the following geographical areas: Spain, Hispanic America, Equatorial Guinea, and portions of the United States (namely the Southwest and Florida). When used in the broader sense to include areas where the local culture has been heavily impacted by Hispanic influences, the former Spanish East Indies colonies of Philippines and to a lesser extent, Guam are also included.

The terms are derived from the Latin word Hispanicus ("Spanish") which refers to anything pertaining to the Roman province of Hispania ("Spain"). In addition to the general definition of Hispanophone, some groups in the Hispanic world make a distinction between Castilian-speaking and Spanish-speaking, with the former term denoting the speakers of the Spanish language—also known as Castilian—and the latter the speakers of the Spanish or Hispanic languages (i.e. the languages of Spain or the languages of the Hispanic nations).
