The owner of the smallest penis will win £325, a crown and a sash at the competition in New York.
However, organisers at the Kings County Saloon are struggling to find entrants and have put out a call for "exemplary small penises" from around the world.
It claimed to be the "first ever conference for the celebration and acceptance of small penises everywhere".
They've opened up a website which lets anyone nominate their friends for the honour and video submissions will be accepted.
The party was launched to highlight the stigma of body shaming and promised to involve nudity – "and may contain nuts".
