Alicia Keys -- Anyone Want My TRAMPOLINE?

Alicia Keys is gutting the 9,000 sq. ft. mansion she just sold on Long Island -- selling off its innards piece by piece next week -- and TMZ has obtained pics of the luxury loot ... including a trampoline!

A rep for American Auctions -- the company behind the sell-off -- tells TMZ the auction's scheduled to take place on Sunday, May 22nd ... and you can expect to bid on everything from Alicia's furniture, fitness equipment, pool table, and trampoline ... to her creepy doll collection.

And yes, that's a samurai sword on that table -- but sadly, it's unclear if that's also for sale.
