Slaughterhouse Island Campground is a boat-in only island campground located at the mouth of the Sacramento Arm of Shasta Lake, offering a scenic escape popular with boaters and houseboat visitors.

While boat-in campsites were previously available on the island, they have been removed and no facilities currently remain on the island itself.

The island is named after the historic Endicott Slaughterhouse and Meat Market and remains a popular destination for water-based recreation and day visits.
