The invention relates to user interfaces for sharing contextually relevant media content. The present disclosure generally relates to managing and sharing contextually-relevant media content. In someembodiments, a device receives an input, and in response, displays a suggested collection of media items for sharing with a recipient, wherein the collection is relevant to a message conversation withthe recipient. Subsequent to displaying the suggested collection, the device transmits a message to the recipient as part of the message conversation that provides access to the at least a portion ofthe suggested collection of media items. In some embodiments, a device receives an indication, from an external device, that a first user has shared a first collection of media items with a second user. Subsequent to receiving the indication that the first user has shared the first collection of media items with the second user, the device outputs a prompt to share, with the first user, one or more suggested media items.
