"Ensign Ro" is the 103rd episode of the American science fiction television series Star Trek: The Next Generation. The third episode of the fifth season.

The crew is unsettled by the arrival of Ensign Ro, a disgraced Starfleet officer of Bajoran origin. Although Ro was previously court-martialed for disobeying orders on an away mission, resulting in the deaths of eight crew members, Starfleet admiral Kennely has pardoned and assigned her to the Enterprise. Her ostensible mission is to persuade Bajoran rebels to stop attacking and raiding Federation colonies. But Picard soon learns that the rebels, displaced from their home-world by the Cardassians some 40 years ago, were not to blame for the attacks- and that Kennely's orders to Ro are very different than those he conveyed to Picard.

The Solarion Four settlement is destroyed, and the Bajorans claim responsibility. The world of Bajor was annexed by the Cardassians generations ago, and the Bajorans have been refugees ever since, and apparently some of them are using terrorism to draw attention from the United Federation of Planets.

Picard meets with Admiral Kennelly, who tells him that the Bajoran responsible is a terrorist named Orta. Picard's mission is to find Orta, and to send him back to the Bajoran settlement camps where he can do less damage.

Kennelly assigns a controversial person to assist Picard: Starfleet Ensign Ro Laren, a Bajoran whose reputation is very poor. Kennelly insists she can help, and she comes aboard the Enterprise.

Despite a difficult attitude, Ro works with the crew to locate Orta. Ultimately, they head to the third moon of Vallor One where they believe he is based.
