PostEurop is the association of European public postal operators, one of the constituent unions of the Universal Postal Union. PostEurop was created in 1993 to simplify the exchange of mails in Europe, a task previously undertaken by the European Conference of Postal and Telecommunications Administrations (CEPT, from its French acronym). A smaller but similar organization is the Small European Postal Administration Cooperation.

PostEurop's headquarters are in Brussels, Belgium.

Since 1993 PostEurop has co-ordinated the annual issue of Europa postage stamps, previously a CEPT function.
