How to Say Hi in Portuguese
Portuguese is spoken by over 250 million people across Brazil, Portugal and parts of Africa and Asia — and saying hi is wonderfully easy. You really only need two words: the breezy Oi and the all-purpose Olá. Knowing when to use each makes you sound natural anywhere in the Portuguese-speaking world.
The Two Essential Greetings: Oi and Olá
Oi — pronounced oy (like “oyster”)
Olá — pronounced oh-LAH (stress on the second syllable)
Oi is the casual, friendly hi that you will hear constantly in Brazil, where it is the default greeting among friends, family and even on the phone. Olá is the more neutral, polite hello — equally at home in formal and informal settings, and the standard everyday greeting in Portugal.
When in doubt, Olá is always a safe choice.

All the Ways to Say Hi in Portuguese
| Portuguese | Pronunciation | When to Use |
|---|---|---|
| Oi | oy | Casual hi (very common in Brazil) |
| Olá | oh-LAH | All-purpose hello, formal or informal |
| E aí? | ee-ah-EE | What’s up? (Brazil, very casual) |
| Tudo bem? | TOO-doo bayn | All good? / How’s it going? |
| Tudo bom? | TOO-doo bohn | Everything good? (casual) |

| Alô? | ah-LOH | Hello? (on the phone) |
Brazilian vs. European Portuguese
The biggest difference between Brazil and Portugal is the popularity of Oi:
- Brazil: Oi is everywhere — casual, warm and the go-to greeting. E aí? (“what’s up?”) is the ultra-casual version among friends.
- Portugal: Olá is the everyday standard. Oi exists but feels more Brazilian; you will more often hear Olá or Viva as a friendly greeting.
Pronunciation also differs: Brazilians soften the “te” and “de” sounds into “chee” and “jee” (so boa noite sounds like “noy-chee”), while European Portuguese keeps a crisper “t” and “d” and tends to swallow unstressed vowels.
Time-of-Day Greetings
Like many languages, Portuguese has greetings tied to the clock:
| Time | Greeting | Literal |
|---|---|---|
| Morning (until ~noon) | Bom dia | Good day |
| Afternoon (noon–sunset) | Boa tarde | Good afternoon |
| Evening/night (after dark) | Boa noite | Good night |
Note that dia (day) is masculine, so it takes bom, while tarde and noite are feminine and take boa. Boa noite serves as both a greeting after dark and a farewell at bedtime.
Pronunciation Tips
- There is no “h” sound in Portuguese. Olá is “oh-LAH,” never “hoh-lah.”
- The accent mark matters. The á in Olá shows the stress lands on the last syllable.
- Nasal sounds are key. Words like bom and bem have a nasal ending — let the sound resonate through your nose, closer to “bohn” and “bayn” than a hard “m.”
- Tudo bem? literally means “all well?” and doubles as both a greeting (“how’s it going?”) and a question. The standard reply is Tudo bem! or Tudo bom! — using the same words to answer.
Cultural Notes
Greetings in the Portuguese-speaking world are warm and relational. In Brazil especially, a hi often comes with a hug or a kiss on the cheek (one or two, depending on the region) among friends. Oi, tudo bem? — “Hi, how’s it going?” — is the friendly all-purpose opener, and people genuinely expect a brief, positive reply before moving on. Lead with Olá in professional or first-time encounters, and switch to Oi once the vibe is relaxed.
Frequently Asked Questions
How do you say hi in Portuguese?
Say 'Oi' (pronounced oy) for a friendly, casual hi — it is extremely common in Brazil. For a more universal greeting that works formally and informally, say 'Olá' (oh-LAH), which is the standard 'hello' across both Brazil and Portugal.
How do you pronounce Oi and Olá?
'Oi' is pronounced oy, exactly like the start of the English word 'oyster.' 'Olá' is oh-LAH, with the stress on the second syllable and the accent mark showing where the emphasis falls. The 'h' does not exist in Portuguese, so never add one.
What is the difference between Oi and Olá?
'Oi' is casual and warm, used among friends, family and in relaxed settings — it dominates in Brazil. 'Olá' is more neutral and polite, fine for strangers, formal situations and is the default in Portugal. When unsure, 'Olá' is always safe.
Is Oi used in Portugal or only Brazil?
'Oi' is overwhelmingly Brazilian. In Portugal people do use it casually, but 'Olá' is far more common there as the everyday greeting. Brazilians say 'Oi' constantly — even when answering the phone — while the Portuguese prefer 'Olá' or 'Está?' on calls.
How do you say good morning, afternoon and evening in Portuguese?
Use 'Bom dia' (bohn JEE-ah) for good morning, 'Boa tarde' (BOH-ah TAR-jee) for good afternoon, and 'Boa noite' (BOH-ah NOY-chee) for good evening or good night. These time-based greetings are polite and used throughout the day.
