The peninsula on which the community of Belle Terre is situated has been known as Mt. Misery since the 17th century. Before Belle Terre's modern existence, the area was referred to as Mt. Misery Point. By comparison, the lower portion of the peninsula, which is currently a section of the neighboring village of Port Jefferson, was referred to as Mt. Misery Neck.
Throughout the 1700s and 1800s, the bulk of the peninsula was owned by the Strong family, who had their Oakwood estate in its Mt. Misery Neck section. The first known dwelling in contemporary Belle Terre was a shack constructed by an African-American affectionately known as Uncle Mott in the 1800s. This house was the subject of a painting by local artist William Moore Davis.
