It is a topic that feels awkward to bring up at a dinner party, but if you're traveling or moving to the Southern Hemisphere, you need to understand it. Legally. Most people assume there is some kind of global standard. There isn't. Not even close. When we talk about the age of consent in South America, we are looking at a patchwork of laws that range from surprisingly lenient to strictly protective.
Laws change. Cultures clash.
If you look at a map of South America, you might expect a uniform Catholic-influenced legal code across the continent. That’s a mistake. You’ve got countries like Argentina and Brazil that have undergone massive legal overhauls in the last two decades, moving away from older "morality" based laws toward a framework focused on "sexual integrity." It’s a subtle shift in wording that changed everything for prosecutors.
Why 14 is the Magic Number (Mostly)
For the longest time, 14 was the standard. Across a huge chunk of the continent, the age of consent in South America has historically hovered around this mark.
Take Peru. For years, the legal age was 14. Then it shifted. Then it got complicated. Under the Peruvian Penal Code, specifically Article 173, the age of consent is generally 14, but there are massive "buts" involved. If there is a position of authority or trust involved, that number effectively doesn't matter; the law will come down on the older party like a ton of bricks. It’s about the power dynamic, not just the birthday.
Bolivia is similar. The age is 14. But honestly, the legal reality on the ground in La Paz is often different from what’s written in a dusty book. There is a heavy emphasis on "estupro" (statutory rape), which in many South American jurisdictions refers specifically to the seduction of a minor between the ages of 14 and 18 through deceit.
The Brazil Exception
Brazil is the heavyweight of the continent, and its laws reflect a very modern, very aggressive stance on child protection. In Brazil, the age of consent is effectively 14. This is governed by the "Estatuto da Criança e do Adolescente" (ECA) and the Penal Code.
Here is where it gets tricky: Article 217-A of the Brazilian Penal Code.

It defines "vulnerable" individuals. Anyone under 14 is considered a vulnerable person. Period. It doesn't matter if there was consent. It doesn't matter if they looked older. It doesn't matter if the person lied about their age. In the eyes of the Brazilian state, a 13-year-old cannot legally consent under any circumstances. This is what lawyers call praesumptio iuris et de jure—a legal presumption that cannot be rebutted.
The Confusion Around Argentina and Chile
Argentina is fascinating because its legal system is quite progressive compared to its neighbors. The age of consent in South America usually gets lumped together, but Argentina’s "Ley de Integridad Sexual" (Law 25.087) makes a clear distinction.
The age is 13.
Wait. 13? Yes. But don’t let that number fool you.
While 13 is the technical floor, Argentine law includes a concept called "corrupción de menores." If an adult’s actions are deemed to "corrupt" the minor—even if the minor is 14 or 15—the adult can still face severe prison time. It’s a "sniff test" law. If it looks like exploitation, the court treats it as exploitation.
Chile, on the other hand, had a long-standing age of 14. However, recent legislative pushes have tried to align Chilean law more closely with international standards like those suggested by the UN. In Chile, sexual activity with someone under 14 is always a crime. Between 14 and 18, it becomes a crime if there is "abuse of a situation of vulnerability."
Essentially, if you are 25 and dating a 15-year-old in Santiago, you are walking on a razor-thin legal tightrope. One slip, and you’re looking at a felony.
Close-in-Age Exemptions: Do They Exist?
In the United States, we call them "Romeo and Juliet" laws. They exist to prevent a 17-year-old from becoming a sex offender because they dated a 15-year-old.

Does this exist when looking at the age of consent in South America?
Rarely in the way Americans think of it.
- Uruguay: Known for being the most liberal country in Latin America. Their age is 15. They tend to be more pragmatic about teenage relationships, but the law still favors the younger party.
- Colombia: The age is 14. The Colombian Constitutional Court has ruled on several occasions that consensual sex between minors (both under 14) is not a criminal matter but a developmental and educational one.
- Ecuador: They keep it at 14. But like their neighbors, the penalties jump exponentially if the age gap is significant.
The reality is that "Romeo and Juliet" exceptions are often handled at the discretion of a judge rather than being a hard-coded statute. If the age gap is less than 3 years, many South American prosecutors simply won't bring a case unless there’s evidence of coercion. But—and this is a big but—you cannot bank on that.
The Cultural vs. Legal Divide
You’ve probably heard stories about rural areas in the Andes or the Amazon where people marry young. This is the "law of the land" vs. "law of the state" conflict.
In some indigenous communities in Paraguay or Peru, traditional customs might allow for unions that the central government in Lima or Asunción would call illegal. However, international human rights pressure has forced these governments to be stricter. You cannot claim "customary law" as a defense for statutory crimes in a federal court anymore.

Venezuela is a mess right now for a lot of reasons, and legal enforcement is one of them. While the age of consent is technically 16 (one of the highest on the continent), the breakdown of the judicial system means that enforcement is wildly inconsistent. This creates a dangerous environment where the law exists on paper but offers very little actual protection—or, conversely, can be used as a tool for extortion.
Practical Knowledge for Travelers and Expats
If you are navigating the legalities of the age of consent in South America, you need to stop thinking about "the age" and start thinking about "the gap."
- Assume 18 is the safe harbor. While the legal age of consent is lower in most countries (14 in many), 18 is the universal age of majority. Any contact with someone under 18 carries inherent legal risk in a foreign jurisdiction.
- ID is not always reliable. In many South American countries, "Cédulas" (ID cards) are easily faked or altered. Relying on a verbal "I'm 18" is a recipe for a legal nightmare.
- The "Abuse of Authority" trap. Even if the person is above the age of consent, if you are their teacher, boss, or even a wealthy tourist compared to a local in poverty, a judge may rule that consent was impossible due to the power imbalance. This is a huge factor in Colombian and Brazilian law.
- Local Legal Counsel. If you find yourself in a situation where you are unsure, do not Google it and hope for the best. Statutes change. For example, Brazil's 2009 reform completely rewrote their sexual crimes chapter.
The age of consent in South America is a reflection of a continent in transition. It is moving away from old-school patriarchal codes—where "honor" was the thing being protected—and toward modern human rights frameworks where "autonomy" and "protection of the vulnerable" are the priority.
Don't let the lower numbers (like 13 or 14) fool you into thinking these countries are lax. They aren't. In many ways, because the laws are based on "integrity" and "vulnerability," they are actually more flexible for prosecutors to use against adults than the rigid "bright line" laws in the North.
Critical Next Steps
If you are researching this for academic or travel purposes, your next move should be to check the specific Penal Code of the country in question via their official government portal (often the Ministerio de Justicia). Do not rely on Wikipedia maps, which are frequently outdated. Specifically, look for terms like atentado contra el pudor or violación de la libertad sexual to see how the specific country defines these boundaries. If you are an expat, register with your local embassy; they often provide handouts on local laws that cover these exact nuances to keep citizens out of foreign prisons.
