"Sins of the Father" is the 65th episode of the American science fiction television series Star Trek: The Next Generation and the 17th episode of the third season.
Set in the 24th century, the series follows the adventures of the Starfleet crew of the Federation starship Enterprise-D. In this episode, the Enterprise's Klingon Chief of Security, Lt. Worf, challenges the Klingon High Council's accusation that his father was a traitor.
This is the first of four appearances of Worf's brother Kurn, each played by actor Tony Todd, in the Star Trek franchise; Kurn last appears on the series Star Trek: Deep Space Nine in the episode "Sons of Mogh" (broadcast February 12, 1996).
