Here are a few different ways to look at it:
* Official Languages: There are about 67 countries where English is an official language. This means it's used in government, education, and official documents.
* Widely Spoken: English is widely spoken in many more countries than just those with it as an official language. It's estimated that over 1.5 billion people speak English as a first, second, or foreign language. This includes countries like India, Nigeria, and the Philippines, where English is widely used in education, business, and media.
* Native Speakers: If we only look at countries where English is the primary language of most people, that number is much smaller. There are about 10-15 countries where English is the native language of the majority, including the United States, Canada, Australia, and the UK.
Ultimately, the answer depends on your definition of "speak English."
