Club Organza is an erotic party venue at Laan van Duuring 1 in Breukelen, in the province of Utrecht, just off the A2 between Breukelen and Maarssen. It calls itself an institution of 25 years' standing, and a number of well-known Dutch kinky parties began here.

Organza holds a definitive municipal licence to run parties of an erotic character, which is what lets it operate as a room other organisers hire as well as running its own nights. The main floor holds up to 350 people and has a large part-raised dance floor with a cage and a dance pole, a double bar, a raised DJ booth, a full sound system, a laser light show and a projection screen. Upstairs is a lockable erotic room, and there is a lockable, professionally fitted SM studio, guest showers, lockers, and a covered heated outdoor terrace with its own DJ booth. For parties that are not erotic, those rooms are simply screened off.

There are no weekly opening hours: the club opens for the events in its own agenda, which mixes its own parties with visiting brands. Entry is through a staffed door with a detection gate and a cloakroom, and there is a large free private car park behind a barrier. The telephone is not answered on Mondays.
