Betazed is a planet in the fictional television and book series Star Trek. The planet is populated by a species of telepathic humanoids, the Betazoids. They were first brought into existence on the series when a half Human, half Betazoid character named Deanna Troi was introduced as ship's counselor on the Star Trek: The Next Generation television show.

In the final year of the Dominion War, Betazed was conquered by the Dominion. It is presumed that it was returned at the end of the war.
