A lesbian triangle, also known as a love triangle, is a romantic relationship dynamic that involves three individuals, typically two women and a third person who is often a woman as well. This setup can lead to complex emotional interactions, conflicts, and personal growth. In the context of lesbian relationships, the term "lesbian triangle" or "love triangle" has been used to describe a situation where two women are in a romantic relationship, and a third woman becomes involved, either as a rival for one of the partner's affections or as a means of exploring one's own desires.

The dynamics of a lesbian triangle can vary greatly depending on the individuals involved and their personal preferences. In some cases, all three individuals may be romantically and sexually involved with each other, while in other cases, the relationships may be more fluid and subject to change.
