To determine the coldest region of the atmosphere from the given options, let’s analyze each term briefly:

1. **Stratopause**: This is the boundary between the stratosphere and mesosphere. Temperatures in the stratosphere increase with altitude due to the absorption of UV radiation, but there is a point where the temperature peaks before it decreases again in the mesosphere.

2. **Tropopause**: This is the boundary between the troposphere and the stratosphere. The troposphere, where weather occurs, generally gets colder with altitude, reaching a point at the tropopause where temperatures stabilize.

3. **Mesopause**: This is the boundary between the mesosphere and the thermosphere. It is known to be the coldest point in the atmosphere, with temperatures dropping to around -90°C.

4. **Thermopause**: This boundary separates the thermosphere from the exosphere, where temperatures can rise significantly due to solar radiation, meaning it is not the coldest region.

### Conclusion
The coldest region among the listed options is the **Mesopause**.
