Chris Brown -- A Terrible Neighbor ... Even In Hawaii

Chris Brown took his bad-neighbor ways on vacation ... throwing a huge house party inside his rented Hawaiian mansion ... and pissing off a slew of neighbors in the process.

CB was in the Aloha state last week for a gig -- plus some graffiti fun -- and rented a sick pad in Honolulu. Check out the pics ... we're talkin' 5,100 square feet, pool and spa for $2,450 per night.

But CB didn't start out the best tenant ... sources connected to the situation tell us the first night Chris was in town he threw a giant shindig -- and neighbors were so pissed they called the owner of the house to complain.

The landlord took note, but didn't give Chris the boot. Did we mention the $2,450/night? We're told Chris and his entourage were at the house for a week and there were no further incidents.

As we reported, right after Chris got back from Hawaii ... his L.A. neighbors also complained about noise, but they called cops.
