'James Bond' Star Timothy Dalton -- Cops Shut Down MASSIVE Rager ... Thrown By Son

EXCLUSIVE

When the cat's away ... his son will throw a MASSIVE house party -- at least that's what happened to Timothy Dalton -- and the whole backyard bash in Hollywood was shut down by cops.

Law enforcement sources tell us they were dispatched around 10:30 PM Saturday after neighbors complained about the massive group -- 300 strong -- waiting outside a party thrown by 17 year-old Alexander Dalton -- whose mom is no stranger to ragers ... Oksana Grigorieva.

Apparently a fight also broke out, so cops rushed over to break things up ... they even had a helicopter as back up.

Timothy wasn't home -- and officers made everyone leave in a hurry.

No arrests were made ... but you don't wanna piss off Bond, James Bond.
