"Black Market" is the fourteenth episode of the second season of the reimagined Battlestar Galactica television series. It aired originally on the Sci Fi Channel on January 27, 2006. In the episode, Apollo's investigation of the fleet's black market becomes intertwined with his involvement with a prostitute. The episode was a disappointment both to executive producer Ronald D. Moore and to critics, several of whom called it the series's worst episode.

Haunted by his near-death experience after ejecting from the Blackbird, Apollo begins sleeping with Shevon, a prostitute on Cloud Nine who reminds him of his pregnant girlfriend who died in the Cylon attack on the Twelve Colonies. Dee asks Apollo whether their relationship is going anywhere; he brushes her off.

President Laura Roslin decides to crack down on the black market within the fleet. Commander Jack Fisk at first advises against it but then volunteers Pegasus to take the lead. Fisk is later found garrotted in his quarters. Assigned to investigate the murder, Apollo discovers Fisk was heavily involved in the black market, and that Vice President Gaius Baltar and Colonel Saul Tigh were among Fisk's trading partners. Roslin privately asks Baltar to resign; the suggestion insults Baltar and redoubles his determination to stay in office.

Responding to an emergency call from Shevon, Apollo rushes to Cloud Nine to find her bruised and distressed. Thugs enter Shevon's room and attack Apollo. As he is being strangled, a gangster tells Apollo to stop investigating Fisk's murder, threatens Shevon and her daughter Paya if he refuses, and knocks Apollo out. Apollo wakes to find Shevon and Paya gone and the wielder of the garrote murdered.
