A Bajoran wedding is a ceremony of the marriage of two people that follows Bajoran traditions.
Leeta wanted her wedding to be traditional, something which Rom agreed to. (DS9: "Ferengi Love Songs")
Captain Benjamin Sisko officiated at Rom and Leeta's wedding in late 2373. The wedding involved recitations in the Bajoran language, while the couple drank from a bowl. (DS9: "Call to Arms")
Benjamin Sisko and Kasidy Yates were supposed to have had a traditional Bajoran wedding in late 2375, but, wishing for a quiet ceremony, were married by Admiral William Ross instead. (DS9: "Penumbra", "'Til Death Do Us Part")
