To determine which of the given compounds is a strong base, we can analyze each option based on their properties:

1. **NaOH (Sodium Hydroxide)**: This is a strong base that completely dissociates in water to produce OH⁻ ions.

2. **NH₄OH (Ammonium Hydroxide)**: This is a weak base that partially dissociates in water.

3. **Ammonia (NH₃)**: While ammonia can act as a base, it is considered a weak base because it does not fully dissociate in water.

4. **CH₃OH (Methanol)**: Methanol is an alcohol and does not exhibit basic properties.

### Final Answer
The strong base among the given options is **NaOH**.
