TMZ has learned cops showed up at Kirsten Dunst's Hollywood Hills home last night -- after the house's silent alarm went off.

Though she has had a stalker show up on her property in the past, this time it was Dunst herself who accidentally tripped the alarm.

We're told she was happy to see the officers -- but they left without incident.
