Aromantic (commonly shortened to aro) is an orientation defined by little to no romantic attraction, the prefix a- meaning not or lack of in Greek.

Being aromantic does not mean that one is unable to experience sexual attraction or any other type of attractions. An aromantic individual can have any sexual orientation. They may identify with a sexual orientation in addition to the label of aromantic to specify who they're interested in sexually, if anyone. For example, a heterosexual aromantic individual is sexually attracted to individuals of a different gender, but is not romantically attracted to any gender. Some aromantic individuals are also asexual (aroace), meaning they experience neither sexual nor romantic attraction.

Romantic dispositions among aromantic individuals can vary. Some aromantic individuals may still have or seek romantic relationship(s) despite not feeling romantic attraction to anyone (cupioromantic). This could be for many reasons, such as for their own pleasure, state benefits, household aid, or feeling that one's attraction is not an important aspect to partaking in their romantic relationship(s). Other aromantic individuals may be repulsed by the concept of romance. Terms like romance-repulsed, romance-indifferent, romance-favorable, or romance-ambivalent are commonly used to describe these attitudes.

A common misconception is that all aromantic individuals lack emotions, lack the ability to form social connections, or are loveless. In reality many aromantic individuals are capable of feeling love, and can meet their emotional needs via queerplatonic, platonic, familial, or other non-romantic relationships. Other aromantic individuals may not desire partners of any kind, and may identify as nonamorous. Some aromantics embrace the loveless label and reject the idea that love is necessary for their own wellbeing and happiness.
