Yep, it's called rim tape, and it protects the tube from the sharp edges of the spoke holes in the rim, and possibly from the ends of the spokes.
You can buy it at any bike store, but in a pinch I've also used narrow adhesive fabric bandage/sports tape. However, the latter isn't as thick and might not be as durable in the long run.
