Onion Routing is a method used for anonymous communication over wide area networks. Much like the heart of an onion is wrapped in many layers, messages sent through Onion Routing are wrapped in layer after layer of encryption. Each layer of encryption corresponds to a stop on the route and the layer is peeled away (decrypted) before being passed forward. The very last layer of encryption is removed by the recipient and the message is revealed.
