A fictional culture in Star Trek. True Trills consist of a humanoid host and a worm-like symbiote that lives inside the abdominal cavity. There are at least two traditional host species; other races such as Humans can only serve as a temporary hosts with medical assistance.

The host has the benefit of the symbiote's lifetime of wisdom and experiences through several previous hosts. Each symbiote has its own name, which becomes part of the host's identity. Joined trills have unique personalities blended from both beings.
Star Trek DS9 had two Trills among the main characters. Both Ezri and Jadzia were joined to Dax.
