"The Child" is the first episode of the second season of the American science fiction television series Star Trek: The Next Generation, the 27th episode overall. It was originally released on November 21, 1988, in broadcast syndication. The story was originally written by Jaron Summers and Jon Povill for the cancelled late 1970s series Star Trek: Phase II. Due to the tight deadlines caused by the 1988 Writers Guild of America Strike, the producers of The Next Generation searched the records of that earlier television project, resulting in the script being amended by show runner Maurice Hurley.

Set in the 24th century, the series follows the adventures of the crew of the Federation starship Enterprise. In this episode, ship's Counsellor Deanna Troi (Marina Sirtis) becomes pregnant by an alien entity and gives birth to a mysterious child. This causes problems for the Enterprise, which is transporting dangerous plague strains. The child's presence on the ship begins to endanger the crew due to effects on a virus sample being transported by the ship. It sacrifices its physical body, turning back into an energy being, telling Troi why it visited before departing.

Being the first episode of the second season, "The Child" was the first episode to feature Diana Muldaur as Doctor Katherine Pulaski and Whoopi Goldberg as Guinan. Director Rob Bowman was allowed to use additional camera equipment to improve the style of filming, resulting in a change to the opening shot of the episode. It was watched by 10.9 million viewers, but critics held a negative opinion of the episode saying that there was no ongoing effect to Troi. Further criticism also compared the means of the character's pregnancy to rape, and stated that the reactions of the other crew-members were irrational.
