David Sears II was a prominent 19th century Boston philanthropist, merchant and landowner. He developed a substantial part of nearby Brookline, Massachusetts, including building the Christ's Church in Longwood, and was associated in the erection of the St Paul's Cathedral. In addition, Sears purchased some 200 acres (0.81 km2), which he developed into the village of Longwood.

Sears also served as a Massachusetts Representative and Senator on and off between the years of 1816 and 1851. In 1844 his gift of $10,000 rescued Amherst College during a difficult time and marks the beginning of the Sears Foundation of Literature and Benevolence.

His great great grandson was John W. Sears.

His house on Beacon Hill is now the location of the Somerset Club.
