Polyamory is the practice of, or the desire for, romantic relationships with more than one partner at the same time, with the informed consent of all partners involved. Some people who identify as polyamorous believe in consensual non-monogamy with a conscious management of jealousy and reject the view that sexual and relational exclusivity (monogamy) are prerequisite for deep, committed, long-term, loving relationships. Others prefer to restrict their sexual activity to only members of the group, a closed polyamorous relationship that is usually referred to as polyfidelity.
A ménage à trois is a domestic arrangement or committed relationship consisting of three people in polyamorous romantic or sexual relations with each other, and often dwelling together. The phrase is a loan from French meaning "household of three". Contemporary arrangements are sometimes identified as a throuple, thruple, or triad.
Open marriage is a form of non-monogamy in which the partners of a dyadic marriage agree that each may engage in extramarital sexual or romantic relationships, without this being regarded by them as infidelity, and consider or establish an open relationship despite the implied monogamy of marriage. There are variant forms of open marriage such as swinging and polyamory, each with the partners having varying levels of input into their spouse's activities.
Polyfidelity is a type of non-monogamous, relationship in which all members are recognized as equivalent to the other partners and comply to restrict sexual and romantic relationship activities to exclusively only other members within the group.

Non-monogamy is an umbrella term that describes a relationship arrangement where one or more partners are not sexually and/or romantically exclusive to each other. Monogamy and nonmonogamy are not strictly binary categories, but rather exist on a continuum encompassing various degrees of exclusivity and openness. Another key characteristic that distinguishes different forms of nonmonogamous relationships is whether they are practiced with the knowledge and consent of all involved parties.
Terminology within polyamory looks at the evolution and meaning of the word "polyamory" itself, as well as alternative definitions and concepts which closely relate to it.
Polygamy is not legally recognised in Australia. Legally recognised polygamous marriages may not be performed in Australia, and a person who marries another person, knowing that the previous marriage is still subsisting, commits an offence of bigamy under section 94 of the Marriage Act 1961, which carries a maximum penalty of 5 years imprisonment. However, the offence of bigamy only applies to attempts to contract a legally recognised marriage; it does not apply to polygamous marriages where there is no attempt to gain recognition for the marriage under Australian law. Whether or not either or both partners were aware of the previous subsisting marriage, the second marriage is void. Foreign polygamous marriages are not recognized in Australia. However, a foreign marriage that is not polygamous but could potentially become polygamous at a later date under the law of the country where the marriage took place is recognized in Australia while any subsequent polygamous marriage is not. While under Australian law a person can be in at most one legally valid marriage at a time, Australian law does recognise that a person can be in multiple de facto relationships concurrently, and as such entitled to the legal rights extended to members of de facto relationships.
Relationship anarchy is the application of anarchist principles to intimate relationships. Its values include autonomy, anti-hierarchical practices, anti-normativity, and community interdependence. RA is explicitly anti-amatonormative and anti-mononormative and is commonly, but not always, non-monogamous. This is distinct from polyamory, solo poly, swinging, and other forms of “dating”, which may include structures such as amatonormativity, hierarchy of intimate relationships, and autonomy-limiting rules. It has also been interpreted as a new paradigm in which closeness and autonomy are no longer considered to create dilemmas within a relationship.

Polyamory in the United States is the practice of, or the desire for, romantic relationships with more than one partner at the same time, with the informed consent of all partners involved, in the United States. Polyamory is a relationship type that is practiced by a minority of the population in the United States, about 4 to 5 percent. According to a 2016 study, 20 percent of singles in the US have attempted some form of consensual non-monogamy at some point of their lives, such as polyamory or open relationships. In a study, polyamorous couples tend to identify as bisexual and pansexual.
Queerplatonic relationships (QPR), also known as queerplatonic partnerships (QPP), are committed intimate relationships between significant others whose relationship is not romantic in nature. A queerplatonic relationship differs from a close friendship by having the same explicit commitment, status, and structure as a formal romantic relationship, whilst it differs from a romantic relationship by not involving feelings of romantic love. The concept originates in aromantic and asexual spaces in the LGBT community. Like romantic relationships, queerplatonic relationships are sometimes said to involve a deeper and more profound emotional connection than typical friendship.
Unicorn hunting is the practice by two people who are in a relationship, usually a heterosexual couple, of seeking a third partner for the relationship temporarily or permanently, usually a bisexual—though occasionally, a lesbian—woman, either to join a threesome or to start a polyamorous relationship. The practice is generally viewed negatively by the polyamorous and LGBT community as a form of fetishisation.
Mononormativity or mono-normativity is the normative assumption that monogamy is healthier or more natural than ethical non-monogamy, as well as the societal enforcement of such an assumption. It has been widely tied to various forms of discrimination or bias against polyamory.
