The different varieties of the Spanish language spoken in the Americas are distinct from each other as well as from those varieties spoken in the Iberian peninsula, collectively known as Peninsular Spanish and Spanish spoken elsewhere, such as in Africa and Asia. There is great diversity among the various Latin American vernaculars, and there are no traits shared by all of them which are not also in existence in one or more of the variants of Spanish used in Spain. A Latin American "standard" does, however, vary from the Castilian "standard" register used in television and notably the dubbing industry. Of the more than 498 million people who speak Spanish as their native language, more than 455 million are in Latin America, the United States and Canada in 2022. The total amount of native and non-native speakers of Spanish as of October 2022 exceeds 595 million.

The Americas, sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World.
