NeNe Leakes Calls Police -- SAVE MY DOG!

NeNe Leakes flagged down a Beverly Hills cop today ... after accidentally locking her dog in her car ... TMZ has learned.

The "Real Housewives of Atlanta" star left her keys in the vehicle and couldn't figure out how to get the door open. The resourceful cop did the trick, and fido was free!

The dog was never in real danger ... it's pretty cold in Bev Hills today.

In case you're interested, it appears the dog in distress was a yorkie named Playa.

Your key, Miss Leakes.
