Over two billion people speak English (as of the 2000s), making English the largest language by number of speakers, and the third largest language by number of native speakers. The United Kingdom and the United States with 67 million and 330 million respectively, have the most native speakers. Additionally, there are 29 million in Canada, 25.7 million in Australia, 5 million in New Zealand, and 5 million in Ireland.

England, a part of the United Kingdom, is the birthplace of the English language, and the modern form of the language has been spreading around the world since the 17th century by the worldwide influence of the United Kingdom, and more recently, the United States. Through all types of printed and electronic media of these countries, English has become the leading language of international discourse and the lingua franca in many regions and professional contexts such as science, navigation and law. The United Kingdom remains the largest English-speaking country in Europe.

Besides the major varieties of English, such as American English, British English, Canadian English, Australian English, Irish English, New Zealand English, and their sub-varieties, countries such as South Africa, India, Nigeria, the Philippines, Jamaica, and Trinidad and Tobago also have millions of native speakers of dialect continua ranging from English-based creole languages to Standard English.

As of 2012, India claims to have the world's second-largest English-speaking population.
