The site's developers said that people with an IQ in this range are "highly intelligent" and communicate and interact best with other intelligent people.
IntelligentPeople.com hopes to give these people the opportunity to meet and form relationships with similar individuals, regardless of location, education and social status.
"Intelligent people usually want a partner who is also intelligent. Everyone wants someone they can talk to," said Trine Jensen, founder of IntelligentPeople.com.
"At general dating sites you have to spend time and energy sorting profiles to find the ones that match your criteria. At IntelligentPeople.com we already make that sorting for you."
The IQ test required for admission is a multiple choice, pattern recognition test consisting of black and white images and is designed to test intelligence while minimising cultural or educational biases.
The site also has a more general community section designed to help members meet other people with high IQs, find a business partner or make new friends.
