Jamie Foxx&039;s annual Halloween party held at his sprawling Thousand Oaks mansion took a violent turn Saturday night when a stabbing took place ... TMZ has learned.

Law enforcement sources tell TMZ ... deputies and paramedics responded to a party at Jamie's house.

A male -- who was stabbed in the neck -- suffered a superficial wound and was treated by paramedics at the scene.

In a chaotic video taken outside the party -- which is organized by Jamie's daughter Anelise -- multiple individuals can be seen in cuffs as hundreds of costumed attendees are directed off the premises.
