In 2374, a Klingon ritual known as the kal'Hyah was held for Worf by General Martok in a Deep Space 9 holosuite. Benjamin Sisko, Miles O'Brien, Julian Bashir, and Alexander Rozhenko attended, under the mistaken impression that the ritual would be the equivalent of a four-day Human bachelor party. (DS9: "You Are Cordially Invited")
In 2375, Benjamin Sisko asked his son Jake to be his best man at his wedding to Kasidy Yates. The younger Sisko noted that his responsibilities would include planning a bachelor party. (DS9: "Penumbra")
In an interview with John Logan featured in Star Trek: Communicator issue 132, Logan indicated that Star Trek Nemesis originally had a line by Captain Jean-Luc Picard that Will Riker's bachelor party was attended by "three Andorians, two Tellarites and a Gorn," though the line did not make it into the final version of the film.
