What is Cristiano Ronaldo's full birth name?

Cristiano Ronaldo’s full birth name is Cristiano Ronaldo dos Santos Aveiro. He was born on February 5, 1985, in Funchal, on the Portuguese island of Madeira, and became known professionally simply as Cristiano Ronaldo or Ronaldo.

The name combines his given name, Cristiano, with family names from both sides of his family. “Ronaldo” was reportedly chosen partly because his father admired Ronald Reagan, who was president of the United States when Ronaldo was born. His father was José Dinis Aveiro, and his mother is Maria Dolores dos Santos Aveiro.

Quiz players often shorten the name to Cristiano Ronaldo dos Santos, but that leaves out Aveiro, the final family name. He is also sometimes confused with Brazilian footballer Ronaldo Nazário, whose full name is Ronaldo Luís Nazário de Lima. The nickname CR7 refers to Cristiano Ronaldo’s usual shirt number and initials.
