Thailand is famous as the “Land of Smiles,” known for its relaxed atmosphere and friendly locals. However, there is one subject that is taken extremely seriously here: The Royal Family.
For Thais, the institution of the monarchy is a pillar of their cultural identity. As a foreign visitor, understanding these rules is not just about being polite—it is essential for avoiding strict legal consequences.
Here is a simple guide to Royal etiquette to help you travel safely and respectfully.
1. The Lèse-majesté Law (Article 112)
You might have heard about this. Thailand has one of the strictest laws in the world regarding the monarchy, known as Lèse-majesté (Article 112).

- What it means: It is illegal to defame, insult, or threaten the King, the Queen, the Heir-apparent, or the Regent.
- The Consequence: Breaking this law can result in a long prison sentence, even for foreigners.
- Tip for Tourists:
- Avoid discussing politics or the Royal Family in public places (including taxis, bars, and restaurants).
- Be very careful with what you post or share on social media.
- Even “jokes” or sarcastic comments can be misunderstood and lead to serious trouble. Just simply show respect.
2. The Royal Anthem in Cinemas
If you plan to watch a movie in a Thai cinema (which is a great experience, by the way!), you will encounter a unique custom.

Before the movie starts, the Royal Anthem will play, and a video honoring the King will be shown on the screen.
- What to do: Everyone in the theater will stand up. You must stand up too.
- Why: It is a gesture of respect to the host country’s culture. Remaining seated can be seen as offensive.
3. Respecting Thai Currency
This is a mistake many tourists make unknowingly. Thai Baht (both banknotes and coins) features the portrait of the King.

In Thai culture, the head is the highest part of the body, and the feet are the lowest and considered “dirty.”
- The Rule: Never step on a coin or banknote to stop it from rolling away.
- Why: Stepping on the King’s image with your feet is considered a grave insult. If you drop money, pick it up with your hands respectfully.
- Also, do not crumple, throw, or tear money in anger.
Summary
Thailand is incredibly welcoming, but showing respect for their most important institution will make your trip much smoother.
