Poly Cocktails was started on Valentine’s Day 2007 by three polyamorous activists and friends as a way to create a social outlet for the local polyamory community in New York. From a small crowd at their first event, held at Madame X in the East Village, Poly Cocktails has grown to become the largest regular social gathering in New York. The event celebrated their 16th anniversary in February 2023 after reconvening in July 2022.

The event is held the second Monday of every month. The event is 21+. RSVPs and COVID-19 vaccinations are mandatory.
