The sinoatrial (SA) node, often referred to as the heart's natural pacemaker, is primarily located in the upper wall of the right auricle (right atrium). This small mass of specialized cells generates electrical impulses that initiate the heartbeat, regulating the heart's rhythm and timing.

### Detailed Explanation

1. **Anatomy**: The SA node is specifically positioned at the junction where the superior vena cava enters the right atrium.
2. **Function**: It serves as the primary pacemaker of the heart, firing impulses that propagate through the heart's conduction system to coordinate heart contractions.
3. **Clinical Relevance**: Proper functioning of the SA node is crucial for maintaining a normal heart rate; any dysfunction can lead to arrhythmias or other cardiac issues.

In summary, the correct answer is **Upper wall of right auricle**.
