Angelina Jolie and Brad Pitt married at the Chateau Miraval in France on Saturday, a spokesman for the couple said.
Jolie and Pitt wed in a small chapel in a private ceremony attended by family and friends.
In advance of the non-denominational civil ceremony, Pitt and Jolie also obtained a marriage licence from a local California judge. The judge also conducted the ceremony in France.
The couple's children took part in the wedding. Jolie walked the aisle with her eldest sons Maddox and Pax. Zahara and Vivienne threw petals, while Shiloh and Knox served as ring bearers, the spokesman said.
The wedding caps years of rampant speculation on when the couple would officially tie the knot. Both publicly said that they planned to.
"It's an exciting prospect, even though for us, we've gone further than that," Pitt said in a November 2012 interview.
"But to concretise it in that way, it actually means more to me than I thought it would. It means a lot to our kids."
This is the second marriage for Pitt, who wed Jennifer Aniston in 2000. They divorced in 2005.
Jolie was previously married to British actor Jonny Lee Miller for three years in the late 90s and to Billy Bob Thornton for three years before divorcing in 2003.
Both Jolie and Pitt are working on movies. Jolie's second directorial effort, the Second World War odyssey Unbroken, will be released in December in the US.
Pitt stars in Fury, also a Second World War drama and due out in the US on October 17.
