Place the potatoes in a pot and cover with cold water. Bring to a boil over high heat and cook for 15-20 minutes until the potatoes are tender when pierced with a fork. Drain and set aside to cool slightly.
While the potatoes are still warm, peel and chop them into bite-sized cubes. Transfer the chopped potatoes into a large mixing bowl.
In a separate small bowl, whisk together mayonnaise, mustard, salt, and black pepper until smooth and well combined.
