Provided is an opportunistic forwarding method and apparatus for a content-based information centric network in a delay tolerant network environment. The opportunistic forwarding method for a content-based information centric network in a delay tolerant network environment having a processor and a memory includes when a first node contacts a second node, updating a first delivery predictability and a second delivery predictability of the first node based on contact record information between the first node and the second node and data that the second node has, updating a first message of the first node by comparing the first message including first interest information and first data that the first node has with a second message including second interest information and second data that the second node has, and delivering the first message of the first node to the second node based on the first and second delivery predictabilities of the first node.
