Embodiments of the present invention address deficiencies of the art in respect to message prioritization and provide a novel and non-obvious method, system and computer program product for social collaborative prioritization of messages in a messaging system. In an embodiment of the invention, a method for social collaborative prioritization of messages can be provided for a messaging system. The method can include receiving a message from a sender as directed to a recipient, determining a value for a different social collaborative criterion based upon an application interaction relationship between the sender and the recipient, transforming the value into a priority for the message, and associating the priority with the message in the messaging system.
