The couple, who announced their engagement in April last year, got married in the Chateau des Conde Saturday, reports Us Weekly magazine.
Berry, who is expecting a child with Martinez, is said to have arrived in a vintage car at the venue where white tents had been erected to ensure the couple's privacy. She wore a simple cream dress.
Berry's daughter Nahle also joined the celebrations.
The actress has been married twice before. She was married to baseball player David Justice for four years before calling it quits in 1997. In 2001, she wed Eric Benet, but parted ways in 2005.
