Shipping (short for "relationshipping"; カップリング Coupling in Japanese) is the belief that two characters in the Pokémon universe are in a relationship, or have romantic feelings that could potentially lead to a relationship. It is generally used as a suffix attached to a word related to a pair of characters (like in PokéShipping). For example, a person who would like to see Ash and Misty as boyfriend and girlfriend would be a PokéShipper, and as a PokéShipper, he or she would support PokéShipping. In addition to "shipping," and "shipper," there are "ship," which is a word for the pairing itself, and "shippy," which is used as an adjective. For example, if Ash and Misty kissed, that moment would be considered PokéShippy.

Some ships in Pokemon crimson include:
