Which Country Has the Most Languages in the World? List of Top 5 Countries with the Most Languages

Do you know how languages were created? How was the first language formed? If you dig deeper, you may find that there are many theories related to the origin of the human language over time.

The Ding-Dong theory, proposed by Jan Baudouin de Courtenay in 1913, suggested that early human languages started with words that sounded like the things they described.

However, this theory has mostly been rejected because there's no real scientific proof, and it's more of a guess than something based on facts.

Now the world has over 7000 languages, but do you know which country has the most languages in the world? Many might guess India or China, but the answer lies in the Oceania region. Still guessing? Let's know!

List of Top 5 Countries with the Most Languages

According to Ethnologue, here are the top 5 countries with the most languages in the world:

1. Papua New Guinea

Papua New Guinea stands out as the world's most linguistically diverse nation, boasting an astonishing 841 languages among a population of approximately 10.7 million people in 2025. The country's rugged mountainous terrain, deep valleys, and numerous isolated islands have historically fragmented communities, limiting inter-group communication and fostering the independent development of countless distinct languages.

2. Indonesia

Ranking second globally, Indonesia is home to a remarkable 721 languages within its vast population of around 285.6 million in 2025. As the world's largest archipelagic state, comprising over 17,000 islands, its geography is the primary driver of this immense linguistic diversity. The isolation created by numerous islands and dense jungles has allowed distinct linguistic groups to develop and thrive independently, often with limited interaction.

3. Nigeria

Nigeria, Africa's most populous nation, secures its place among the top three with 538 languages for its population of roughly 237.5 million in 2025. It is home to over 250 distinct ethnic groups, each with its own language or dialect. While English is the official language due to its colonial past, and major regional languages like Hausa, Yoruba, and Igbo are widely spoken, the vast majority of linguistic variety comes from smaller, often indigenous, communities.

4. India

With 459 languages for its enormous population of approximately 1.4 billion in 2025, India stands as one of the most linguistically diverse nations. This vast diversity is a product of its ancient history, immense geographical expanse, and a multitude of distinct ethnic and cultural groups. Each region often boasts its own set of languages, many of which are officially recognised.

5. United States

The United States, with 364 languages spoken among its population of around 328.2 million in 2020, holds a unique position on this list. Although English emerged as the primary language, many communities have actively preserved their heritage languages, which were brought by different immigrants. Major immigrant languages like Spanish, Chinese, Tagalog, Vietnamese, and Arabic contribute significantly to this count, reflecting the nation's status as a melting pot of cultures.

6. Australia

Australia, with 320 languages for a population of approximately 26.9 million in 2025, also exhibits significant linguistic diversity. Historically, the continent was home to hundreds of distinct Aboriginal and Torres Strait Islander languages, many of which are now endangered or extinct due to colonisation, though efforts are underway to revive them. About 23% of Australia's population speaks a language that isn't English at home. Beyond its indigenous heritage, it is a linguistic melting pot with sizable populations speaking Mandarin, Arabic, Cantonese, Vietnamese, and Italian.

7. China

China, with 308 languages for its immense population of roughly 1.41 billion in 2025, is another giant on the linguistic diversity map. While Mandarin Chinese is the official and most widely spoken language, China is far from linguistically monolithic. Beyond the major Chinese dialects (like Cantonese, Wu, Min, Xiang, Hakka, and Gan), there are hundreds of languages belonging to different language families, such as Tibetan, Uyghur, Zhuang, Mongolian, and Korean, spoken by the country's 55 officially recognised ethnic minorities.

8. Mexico

Mexico, with a population of 304 languages and about 131.8 million in 2025, showed a rich linguistic heritage. Before the arrival of the Spanish, Mesoamerica was the centre of complex cultures, each with its language. When Spanish became a dominant language, many indigenous communities successfully maintained their ancestors' mother tongue. Today, Mexico officially recognises 68 national languages, 63 of which are indigenous. These languages are of different languages like Uto-Aztecan, Mayan and Auto-Affiliate, in different regions, often spoken in different areas or tight-knit communities.

9. Cameroon

Often known as "Africa in miniature" due to its various geography and ecosystems, Cameroon has 281 languages in a population of about 29.81 million in 2025. Hundreds of ethnic groups live within their borders, speaking the various African languages such as Bantu, Adava and Ubangian; linguistic fragments are a natural result. While English and French serve as official languages because of their colonial past, most Cameroonians continue to speak and identify with their indigenous languages.

10. Brazil

Brazil, the largest country in South America, has 240 languages spoken by its population of approximately 212.8 million in 2025. A significant portion of this linguistic diversity comes from its numerous indigenous languages, many of which are spoken by communities in the vast and often isolated Amazon rainforest. In addition to indigenous languages, Brazil's immigration history (e.g., Italian and German), Africa (due to the slave trade), and Asia have also added layers of linguistic variety.

Which Country Has the Most Languages in the World?

The country with the most languages spoken is Papua New Guinea, with a staggering 841 living languages. This linguistic diversity is due to the country's isolated communities, each developing its own distinct language over centuries. Following Papua New Guinea, Indonesia comes in second with 721 languages, and Nigeria ranks third with 538 languages.
