The Gamaliel Thompson House is a former residential structure located at 101 Summit Street in the city of Hudson in westernmost Lenawee County, Michigan.

[4] In 1890, Thompson hired John L. Matthes and Company of Adrian to construct this house at a cost of $6,500.

[2] The Gamaliel Thompson House is a two-and-one-half story wooden structure with a profusion of bays and porches.

The irregularly shaped roof is covered with green painted tin and trimmed with corniced boxed brackets.

A notable feature of the interior is the cherry paneling which lines the library walls, and the elliptical stained glass window in the same room.
