An '''open relationship''' is an [[intimate relationship]] that is sexually or romantically [[non-monogamous]]. An open relationship generally indicates a relationship where there is a primary emotional and intimate relationship between partners, who agree to at least the possibility of sexual or emotional intimacy with other people. The term "open relationship" is sometimes used interchangeably with the term [[polyamory]], but the two concepts are not identical. 

Open relationships include any type of romantic relationship (dating, marriage, etc.) that is open.<ref name="Collective2005" /> 
An "open" relationship means one or more parties have permission to be romantically or sexually involved with people outside of the relationship. This is opposed to the traditionally "closed" relationship, where both parties agree on being with one another exclusively. The concept of an open relationship has been recognized since the 1970s.<ref name="Web MD">{{Cite web |last=Doheny |first=Kathleen |title=The Truth About Open Marriage |url=http://www.webmd.com/sex-relationships/features/the-truth-about-open-marriage |access-date=8 June 2013 |publisher=Web MD}}</ref>
