Pi Kollektiv is a kinky, queer and sex-positive events space on Hans-Böckler-Straße in Langenhagen, immediately north of Hannover. It calls itself Hannover's culture laboratory for unusual events and describes itself, in its own words, as kinky, queer, sex-positive and nonconformist.

Its programme is organised by category — fetish, gothic and stage performance among them — and its events run at its own premises. Recent billings include a female-ruled salon evening and a Halloween ball for what it calls fans of bizarre erotica, dark wave and vampire theatre, with doors from 9pm.

Its invitation is to dance, play and experiment, and it presents itself as a space for culture, dancing and celebration rather than a conventional club. Tickets for individual events are sold through external ticketing.
