As long as people have been falling in love, social norms have prevented some lovers from being together. Forbidden Love applies whenever taboo tries to prevent two individuals from (openly) being in a relationship. This can result in a Secret Relationship, a Suicide Pact, Courtly Love or even Happily Ever After. Compare to Star-Crossed Lovers, which is about specific circumstances separating lovers rather than social norms, although there may be overlap.

- A variation in Star Trek: Deep Space Nine, in the episode "Rejoined": in Trill society, it is taboo for a symbiont host to rekindle relationships with people from previous hosts, including with the host of a symbiont from a prior relationship. This is called a "rejoining", and is strictly forbidden under pain of exile from the Trill homeworld — a punishment which is essentially a death sentence for the symbiont, since there would be no more Trill hosts after their current host dies. In this specific episode, Jadzia Dax and Lenara Kahn struggle with their feelings for each other in the face of this taboo, as the Dax and Kahn symbionts were joined to a previously married couple, Torias and Nilani.
- Selena's "Amor Prohibido" is about this. For unspecified reasons that might be money related, people (including their own parents) disapprove of the relationship.
