Rosie O'Donnell -- Selling Fancy Florida Mansion

Rosie O'Donnell has put her enormous Miami Beach mansion up for sale -- and she's asking for $19.5 MILLION.

Rosie put the Star Island property up for sale today -- just days after her show was canceled on the Oprah Winfrey Network. It's unclear if the real estate move is related to the TV flop.

The home features TWO private guest houses in addition to the main house -- and 203 feet of prime water frontage.

Rosie purchased the 11,000 sq. ft. beachfront property in 1999 for $6.75 million. Apparently, it was a damn good investment.

Thanks to South Beach Condo Blog for the heads up.

Rosie's publicist tells TMZ, the actress now lives in New York full-time -- adding, "She's loved being in Miami for the last 15 years and loved her house on Star Island. Now that her kids are grown with 2 away in private schools there is very limited vacation flexibility and they are not able to use the home as much.."
