"Paradise Lost" is the tenth episode of the sixth season of the American television comedy drama Shameless, an adaptation of the British series of the same name. It is the 70th overall episode of the series and was written by executive producer Etan Frankel and directed by Lynn Shelton. It originally aired on Showtime on March 20, 2016.

The series is set on the South Side of Chicago, Illinois, and depicts the poor, dysfunctional family of Frank Gallagher, a neglectful single father of six: Fiona, Phillip, Ian, Debbie, Carl, and Liam. He spends his days drunk, high, or in search of money, while his children need to learn to take care of themselves. In the episode, Frank and Debbie leave the commune after the latter begins laboring, while Lip's downward spiral continues.

According to Nielsen Media Research, the episode was seen by an estimated 1.60 million household viewers and gained a 0.6 ratings share among adults aged 18–49. The episode received highly positive reviews from critics, who praised the performances, writing and closure to Debbie's pregnancy arc.

At the commune, Frank (William H. Macy) fights the leader, Jupiter (Jeff Kober), in a match on a black liquid. Frank wins the fight, earning him the right to have sex with any woman in the commune. While Frank enjoys his stay, Debbie (Emma Kenney) starts having second thoughts after discovering the laboring methods the commune intends to use on her.

Sean (Dermot Mulroney) has moved in with the Gallaghers, while Fiona (Emmy Rossum) begins planning her wedding. Veronica (Shanola Hampton) and Svetlana (Isidora Goreshter) continue their plans to get married, upsetting Kevin (Steve Howey). He tries to get them a fake ID, but is disappointed when he realizes they married behind his back. Ian (Cameron Monaghan) starts his EMT test, and manages to pass it after impressing the officers. Nevertheless, he lies about his mental health, as he and Caleb (Jeff Pierre) fear he might get passed on.

Lip (Jeremy Allen White) is assigned by Youens (Alan Rosenberg) to grade midterm papers. He also has his interview at an internship; despite arriving unprepared, the interview ends well for him. Later, he is fired from the sorority house after his reckless behavior at the party. Furthermore, he is told by the student council that he will have to attend counseling or face expulsion. Lip also confronts Youens after finding that his contributions to an article were credited to Youens, and insults him after revealing he did not grade the papers. Carl (Ethan Cutkosky) and Dominique (Jaylen Barron) start a relationship, although her father Luther (Peter Macon) disapproves of Carl. He decides to take Carl on a ride-along, which Carl actually enjoys. As Luther goes after a criminal, Carl notices another one fleeing and tackles him.

Fed up with the commune, Debbie (Emma Kenney) asks Frank to get her out of there when she begins laboring, which he does. As they arrive at the Gallagher household, Frank is kidnapped by G-Dog's henchmen and taken away. He is brought to a warehouse, where they plan to torture him. Frank saves himself by claiming he can get them opium. He gets them to the commune, where they get into a shootout with Jupiter, and Frank seizes the opportunity to flee. At the house, the family helps Debbie in safely delivering her baby. Debbie names her child Frances, in honor of Frank. She then leaves in an ambulance, asking to be alone.

The episode was written by executive producer Etan Frankel and directed by Lynn Shelton. It was Frankel's 11th writing credit, and Shelton's first directing credit.
