There are many famous black people. This is a difficult question to answer, because it depends on your definition of fame. Some people might say that the most famous black person is Barack Obama because he was the first African American president of the United States. Others might say that Oprah Winfrey is the most famous black person because she is a successful talk show host and businesswoman. There are also many influential black people who are not as well-known to the general public, such as Martin Luther King Jr. or Malala Yousafzai. So, it really depends on what you consider to be fame.
