Relacionamento vs. relação
While both relacionamento and relação translate to "relationship" in English, usage varies significantly by region. generally, relacionamento is the preferred term for a committed romantic partnership in Brazil, while relação is the standard, everyday term used in Portugal. In Brazil, relação can sometimes refer specifically to the dynamic between people or, in certain contexts, sexual intercourse.
Relacionamento
B1In Brazil, this is the most common and standard word used to describe a committed romantic partnership, such as dating or marriage. It implies a formal status (like specific status updates on social media). In Portugal, relacionamento is understood but often sounds more formal, technical, or distinctively Brazilian, and is less common in casual conversation.
Eles decidiram terminar o relacionamento depois de cinco anos.
(They decided to end the relationship after five years.)
Estou em um relacionamento sério no momento.
(I am in a serious relationship at the moment.)
Um relacionamento à distância exige muita confiança.
(A long-distance relationship requires a lot of trust.)

(Our relationship changed a lot after we got married.)
Não estou procurando um relacionamento agora.
(I am not looking for a relationship right now.)
Relação
B1In Portugal, this is the standard word for a romantic bond; saying you are in a relação is the natural way to say you are dating. In Brazil, while relação is used for romance, it often focuses more on the quality or dynamic of the connection (e.g., a toxic relationship) rather than the status itself, and in medical or formal contexts, it can be short for sexual relations.
A Joana e o Pedro têm uma relação muito bonita.
(Joana and Pedro have a very beautiful relationship.)

(Their relationship did not survive the distance.)

(To have a good relationship, one implies knowing how to listen.)

(She got out of a complicated relationship recently.)
Construir uma relação sólida leva tempo.
(Building a solid relationship takes time.)
Summary
Use relacionamento if you are in Brazil to speak about your dating status or a committed bond. Use relação if you are in Portugal for the exact same meaning. If you use relação in Brazil, you are often describing the *quality* of the bond rather than the status, whereas in Portugal, it is the default word for having a boyfriend or girlfriend.
