Benjamin Thompson (April 22, 1806 – January 31, 1890) was an American farmer and businessman, remembered as the main benefactor of the present-day University of New Hampshire, located in Durham, New Hampshire.

[citation needed] Upon his death in 1890, Thompson left the State of New Hampshire his farm and other properties in Durham.

He also left Warner Farm, which was originally part of the Valentine Hill grant at Oyster River.

The first building constructed, in the center of the new campus, was named Thompson Hall in his honor.

For many years, its profile was used by the school on all documents and memorabilia; it now houses some administrative offices.
