A swim ring (also known as a swimming ring, swim tube, rubber ring, water donut, floatie, inner tube, or, in the United States, a lifesaver) is a toroid-shaped (hence the name "ring" or "doughnut") inflatable water toy.

The swim ring was derived from the inner tube, the inflatable inner part of older vehicle tires.^[1] The inner tube, when inflated, was used as a water toy, and as a floating object to lounge on.
