The Hunger Games actress, 29, exchanged vows with the art gallery director at the weekend.
According to US reports, the couple tied the knot in a mansion in Newport, Rhode Island.
Celebrity guests were said to include Emma Stone, Kris Jenner and Amy Schumer.
The couple got engaged in February, about a year after they started dating.
Last month Lawrence shared their wedding gift list online.
Her list of wedding must-have items, posted on Amazon, included an espresso maker costing 150 US dollars (£120) and a tea kettle priced at 99 US dollars (£80).
She included items for "outdoor entertaining", with string lights and a tundra cooler making the cut.
