"Accession" is the 89th episode of the syndicated American science fiction television series Star Trek: Deep Space Nine, the 17th episode of the fourth season.

Set in the 24th century, the series follows the adventures on Deep Space Nine, a space station located near a stable wormhole between the Alpha and Gamma quadrants of the Milky Way Galaxy. In the episode, Captain Sisko (Avery Brooks) is given a much-appreciated opportunity to relinquish the title of Emissary, but soon comes to regret it.

An ancient Bajoran ship emerges from the wormhole. Its passenger, Akorem Laan, is a revered Bajoran poet who disappeared 200 years ago. Akorem claims to have been chosen by the Prophets, who are worshiped by the Bajorans as gods, as their Emissary—a role thought to belong to Captain Sisko. Sisko, being a human and a Starfleet officer, never felt comfortable being the Bajorans' messiah figure and cedes the title without resistance.

Akorem believes the Prophets brought him back to restore Bajor's traditional caste system, which the Bajoran people abandoned during the 50-year Cardassian occupation so that they could effectively organize a resistance. Akorem tells Major Kira that she must resign her military commission and become an artist, which was her family's traditional profession under the old caste system. Akorem hopes to have the caste system legally enforced by punishments such as deportation. Sisko warns Akorem that caste based discrimination is banned by the Federation Charter and thus would disqualify Bajor from Federation membership, but Akorem trusts in the will of the Prophets.
