Solo polyamory describes a person whose orientation is polyamorous and whose chosen relationship-life-design centres personal autonomy. A solo polyamorous person does not live with a partner, does not pursue partnership escalation by default, often handles finances independently, and does not rank a single partner above others — not because they cannot care deeply for multiple partners, but because they do not centre their identity around a primary-partner role.

Solo poly is sometimes misunderstood as polyamory without partners. The 'solo' refers to the life-design (an autonomous adult life is the centre), not to the relationships themselves. A solo polyamorous person may have several deeply committed partners — what they do not have, by design, is a partner relative to whom they would describe themselves as 'one half' of a unit. The unit is the self.

Solo polyamory overlaps with relationship anarchy but is not identical. RA is a philosophical position on relationships in general; solo poly is a specific configuration. Many relationship anarchists are also solo poly; many solo poly people are not strictly relationship anarchists.

Practical markers commonly cited by solo poly practitioners: living alone (or with non-romantic housemates, not co-habiting with partners); financial independence from partners; making major life decisions on one's own terms without expectation of partner approval; treating dating not as a search for someone to merge lives with but as a question of which relationships to weave into the life one is already building.
