Maison de L'Amitié, French Regency mansion in Palm Beach, United States.

Maison de L'Amitié is a French Regency mansion located on the Palm Beach waterfront with direct Atlantic Ocean access. The main house features multiple wings, numerous bedrooms and bathrooms, and marble flooring throughout the interior spaces.

Robert Dun Douglass of the Dun & Bradstreet family first owned the oceanfront plot, sold in 1930 to tycoon Harrison Williams. Nursing-home magnate Abe Gosman built the French Regency mansion and named it Maison de L'Amitié; after his 2003 bankruptcy it went to auction in 2004, where Donald Trump outbid Jeffrey Epstein at $41.35 million. Trump sold it in 2008 to Dmitry Rybolovlev for $95 million, then a US record for a residence; the house was demolished in 2016.

The name means "House of Friendship", given by nursing-home magnate Abe Gosman, who built the mansion in the 1990s on land once owned by a Dun & Bradstreet family member. The estate was demolished in 2016 and its six acres split into three lots of about two acres, all sold by 2019 for roughly $108 million.

The mansion was demolished in 2016, so there is nothing left to tour; the six-acre oceanfront site was split into three parcels of about two acres each. The southernmost lot, 2.72 acres, went to the 515 North County Road Trust in November 2016 for $34.34 million, and a new house by Bridges, Marsh & Associates was approved there in 2017.

The mansion was demolished in 2016, and the six-acre lot was split into three parcels of about two acres. Sold in 2016, 2017 and 2019 for $34.34 million, $37 million and $37.29 million, they totalled $108.2 million, roughly $13 million more than Dmitry Rybolovlev paid in 2008.
