Apparatus are disclosed for cameras and camera housings for vehicle trailers. An example camera housing for vehicle trailers includes a first body defining an aperture and a second body coupling to the first body to define a cavity. The example camera housing also includes a panel that slides along the first body toward an open position to expose the aperture as the cavity receives a camera and toward a closed position to cover the aperture as the camera is removed. The example camera housing also includes a spring biasing the panel toward the closed position.
