Kensington Palace said the name of the new royal would be announced in due course. Bookmakers have made Albert, Arthur, Jack and Fred the favourite names for a boy.
The baby is the queen's sixth great-grandchild and is behind his grandfather and heir Prince Charles, father William, and siblings George, 4, and Charlotte in line to the throne.
The Duchess of Cambridge, Kate Middleton was admitted to a hospital in London on Monday after going into an early stage of labour.
Both the Duchess and her husband William the Duke of Cambridge had not asked about the sex of the baby in routine checkups as they wanted it to be a surprise.
This is going to be a third child after Prince George and Princess Charlotte.
