Hierarchical Polyamory
A polyamorous structure that explicitly ranks partners — typically a primary above one or more secondary or tertiary partners, with the primary holding more time, decision-making power, and (sometimes) veto rights. Contrasts with egalitarian polyamory and relationship anarchy.
Hierarchy in polyamory is the question of whose relationship gets the bigger seat at the table. Britannica's entry on hierarchical polyamory describes it as a structure in which certain partners are considered to have priority over others, typically organised into primary, secondary, and sometimes tertiary tiers, with primaries receiving the most time, commitment, and decision-making weight. The hierarchy is usually anchored in shared infrastructure: cohabitation, finances, children, marriage, or a long-running primary partnership that predates the others.
The most contested feature is veto power, which gives a primary partner the right to demand the end of a secondary's relationship. More Than Two's secondary's guide documents the practical effects: secondaries find themselves negotiating against rules they had no role in writing, and the threat of a veto can suppress honest disclosure between metamours. Many contemporary poly writers distinguish between descriptive hierarchy (some relationships are simply older or more entangled) and prescriptive hierarchy (one partner formally outranks another by rule), arguing the first is unavoidable while the second is the source of most ethical friction.
Hierarchical polyamory contrasts with egalitarian or non-hierarchical polyamory, where partners deliberately refuse to rank relationships, and with relationship anarchy, which rejects the entire frame of partner categories. None of the three is inherently more ethical than the others; the relevant question for newcomers is whether everyone in the structure has consented to it with full information, including any later-arriving partners who may inherit rules they cannot renegotiate.

Related Terms
- Primary Partner — In hierarchical polyamory and many open-relationship structures, the partner who has the most central, established, and prioritized relationship — typically a long-term spouse or live-in. Not all non-monogamous people use primary/secondary language; relationship-anarchy and egalitarian poly explicitly reject it.
- Secondary Partner — In hierarchical polyamory, a partner whose relationship is real and ongoing but explicitly less central than the primary relationship — usually with less time, planning, or formal commitment. The label is contentious: critics argue it imposes a power imbalance that disrespects the secondary partner's autonomy.
- Relationship Anarchy — A philosophy that rejects rules-based hierarchies between relationships, treating each connection on its own terms rather than slotting it into a pre-defined category. Relationship anarchists typically refuse "primary/secondary" labels and emphasize personal autonomy over social scripts.
