There are 20 sovereign countries where Spanish is an official or de facto national language, plus the US territory of Puerto Rico. They span four continents — one in Europe, one in Africa, and eighteen across the Americas — and together they account for roughly 500 million native speakers, second only to Mandarin Chinese.
The Twenty, Grouped by Region
Taking them by geography rather than alphabetically makes the colonial pattern visible immediately.
Europe (1)
- Spain — around 48 million people; the origin point, though today home to less than a tenth of the world's Spanish speakers.
North and Central America (7)
- Mexico — around 130 million, by far the largest Spanish-speaking nation on Earth
- Guatemala — around 18 million
- Honduras — around 10 million
- El Salvador — around 6 million
- Nicaragua — around 7 million
- Costa Rica — around 5 million
- Panama — around 4.5 million
The Caribbean (2)
- Cuba — around 11 million
- Dominican Republic — around 11 million, sharing Hispaniola with francophone Haiti
South America (9)
- Colombia — around 52 million, the second-largest Spanish-speaking country
- Argentina — around 46 million
- Peru — around 34 million
- Venezuela — around 28 million
- Chile — around 20 million
- Ecuador — around 18 million
- Bolivia — around 12 million
- Paraguay — around 7 million
- Uruguay — around 3.4 million
Africa (1)
- Equatorial Guinea — around 1.7 million
Two South American countries are conspicuously absent: Brazil, which speaks Portuguese, and Guyana, Suriname, and French Guiana, which speak English, Dutch, and French respectively. That single Portuguese exception is the legacy of the 1494 Treaty of Tordesillas, which drew a meridian through the Atlantic and assigned everything east of it to Portugal — a line that happened to clip the bulge of what became Brazil.
The Outlier in Africa
Equatorial Guinea is the only African country with Spanish as an official language, and it is the answer most people miss. It was Spanish Guinea until independence in 1968, one of very few Spanish possessions in sub-Saharan Africa, and it retained the language afterwards.
The country is unusual in several ways. Its capital, Malabo, sits on the island of Bioko, well offshore, while most of its territory and population are on the mainland enclave of Río Muni between Cameroon and Gabon. It has three official languages — Spanish, French, and Portuguese — the latter two adopted to ease membership of regional and lusophone blocs. Spanish is spoken by a large majority of the population, though usually alongside Fang, Bube, or another indigenous language, and it functions primarily as the language of government, education, and media.
Puerto Rico and the Territory Question
Puerto Rico is where the count of "twenty" gets qualified. It is an unincorporated territory of the United States, not a sovereign state, so it does not appear on a list of countries — but with around 3.2 million residents, Spanish as the dominant everyday language, and both Spanish and English holding official status, excluding it entirely misrepresents the Spanish-speaking world.
Most careful sources therefore write "20 countries plus Puerto Rico". The island's status has been the subject of repeated referendums without resolution, and Puerto Ricans are US citizens who cannot vote in presidential elections while resident on the island.
Where Spanish Is Spoken Without Being Official
Official status and actual usage diverge in several significant places.
- The United States — has no official language at federal level, yet somewhere in the region of 40 million people speak Spanish at home. By raw speaker numbers the US ranks among the largest Spanish-speaking populations in the world, ahead of most of the twenty countries on the list.
- Belize — English is the sole official language, a legacy of British Honduras, but a very large share of the population speaks Spanish, and it is surrounded by Spanish-speaking neighbours.
- Andorra — Catalan is the only official language, but Spanish is widely spoken by a population heavily drawn from Spain.
- The Philippines — Spanish was an official language until 1987 and left deep traces in Filipino vocabulary and place names. Chavacano, a Spanish-based creole, is still spoken around Zamboanga.
- Western Sahara — a former Spanish colony and a disputed territory, where Spanish retains a limited presence, particularly in the Sahrawi refugee community.
Running in the other direction, several official Spanish-speaking countries are deeply multilingual. Paraguay is genuinely bilingual: Guaraní is co-official and spoken by a majority of the population, including many with no indigenous ancestry. Bolivia's constitution recognises dozens of official languages alongside Spanish, Quechua and Aymara among them. Peru gives Quechua and Aymara co-official status in the areas where they predominate. And within Spain itself, Catalan, Basque, and Galician are co-official in their respective regions.
Not One Spanish
Spanish is far more internally varied than a single label suggests, and the differences are systematic rather than random.
Voseo
Argentina, Uruguay, Paraguay, and much of Central America use vos instead of tú for the informal singular "you", with its own verb conjugations — vos hablás rather than tú hablas. This is not slang; it is the standard register in those countries, taught and used in broadcast media.
Vosotros
Spain uses vosotros for the informal plural "you". Latin America does not — it uses ustedes for every plural "you", formal or not. This is one of the most reliable ways to tell a European from an American text.
Distinción
Most of Spain distinguishes the sound of c before e or i, and of z, from that of s. All of Latin America and parts of southern Spain merge them, so casa and caza sound identical.
Vocabulary
Everyday nouns diverge sharply. A car is coche in Spain, carro in much of Latin America, auto in the Southern Cone. Words for bus, computer, mobile phone, and juice all differ by region. Standardisation is coordinated by the Association of Academies of the Spanish Language, which brings together twenty-three national academies — an institutional recognition that no single country owns the language.
Spanish Beside Portuguese, English, and French
Twenty countries sounds like a lot until you place it against the other colonial languages, and the ranking depends entirely on which metric you use.
Portuguese is official in nine countries — Portugal, Brazil, Angola, Mozambique, Guinea-Bissau, Cape Verde, São Tomé and Príncipe, East Timor, and Equatorial Guinea — barely half Spanish's count. Yet Portuguese has around 250 million native speakers, because Brazil alone holds over 200 million. Spanish spreads its speakers across twenty states; Portuguese concentrates four-fifths of its in one.
English runs the opposite way: official or de facto in well over fifty countries, but with fewer native speakers than Spanish. Its dominance is as a second language, and the country count reflects the reach of the British Empire into small states rather than large populations. French is official in around thirty countries, heavily weighted toward West and Central Africa, where population growth means its speaker numbers are rising fastest of any major European language. Arabic is official in roughly two dozen states across North Africa and the Middle East.
So Spanish sits in an unusual position: second in native speakers, third or fourth in country count, and unusually mutually intelligible across its whole range. A Mexican, an Argentine, and a Spaniard understand one another without difficulty — which is not something an Arabic speaker from Morocco and one from Iraq can assume.
The Academies That Try to Keep It One Language
Spanish has an unusual institutional arrangement for a language spoken across twenty countries: a network of national language academies that coordinate rather than compete.
The Real Academia Española, founded in Madrid in 1713, is the oldest, but it no longer acts alone. The Association of Academies of the Spanish Language brings together academies from every Spanish-speaking country plus the United States and the Philippines, and major dictionaries and grammars are now published as joint work rather than as Spanish pronouncements.
That shift matters for how the language behaves. Decisions about spelling reform, the admission of regionalisms and the treatment of Americanisms are made collectively, which is a substantial part of why written Spanish has stayed mutually intelligible across an enormous area and a very large number of speakers.
Counting Countries Against Counting Speakers
The two questions give very different answers, and it is worth knowing which one you are being asked.
By countries, the list is fixed at twenty, and it has been stable since Equatorial Guinea's independence in 1968. By speakers, the picture keeps moving: around 500 million native speakers, closer to 600 million including those who speak it as a second or foreign language, and growth driven overwhelmingly by demography in Latin America and by Spanish's position as the most-studied foreign language in the United States.
The mismatch produces the standard trick question. Spain is the source of the language but eleventh or so among Spanish-speaking countries by population; Mexico has nearly three times as many Spanish speakers as Spain does; and the United States, which appears on no list of Spanish-speaking countries, would rank in the top five if it did. For the fuller regional picture, the list of Latin American countries is a useful companion, since it includes Brazil and the non-Iberian territories that a Spanish-language list necessarily leaves out.
