"Q2" is the 19th episode of the seventh season of the American science fiction television series Star Trek: Voyager initially airing on the UPN network. It is the 165th episode of the series overall and is directed by Star Trek: The Next Generation castmember LeVar Burton (Geordi La Forge).

The series follows the adventures of the Federation starship Voyager during its journey home to Earth, having been stranded tens of thousands of light-years away. In this episode, Q (John de Lancie) stops by to leave his undisciplined son (Keegan de Lancie) (conceived at the end of "The Q and the Grey") in the care of his "godmother", Captain Janeway (Kate Mulgrew).

This episode marks the last on-screen appearance of "Q", and features "Q" actor John de Lancie's real-life son Keegan as the young "Q".

Q (John de Lancie) shows up on USS Voyager to introduce Kathryn Janeway (Kate Mulgrew) to her godson, Q Junior (Keegan de Lancie), who now has the appearance of a human teenager. Q Junior is rambunctious and troublesome, causing various incidents across the ship. Q explains to Janeway that the Continuum hoped his son would help stabilize the Continuum but instead started the same type of problems on a much larger scale such as tearing holes in the fabric of space-time. The Continuum blamed Q and plans to turn Q Junior into an amoeba. Q brought him to Voyager to hopefully have Q Junior learn something. Janeway suggests some "father-son" time, but after ten minutes, Q admits that doesn't help as Q Junior had just rearranged the tectonic plates on a nearby planet. Janeway asserts that Q Junior needs to learn there are consequences of his actions.
