4,000,000 (four million) is the number of dominoes set up for Friday, November 15, 2002 in Leeuwarden, which has therefore been named Expressions for Millions.

It is also the first prize (El Gordo) in the Spanish Christmas Lottery in euros.

It was also the prize for correctly answering the first seven questions in the Italian game show Chi vuol essere miliardario? in Italian lire.

This number is equal to 2,0002.

In the Hawaiian language, 4,000,000 is sometimes called "nalowale".[1]
