The John and Maria Adams House is a historic structure near the city of Olmsted Falls, Ohio, United States.

Built in the early nineteenth century, the house was expanded throughout the following several decades, and it has been named a historic site.

Another early resident, John Adams, married Maria Hoadley in 1820,[2] and the oldest part of the present house was built in the same year.

[1] Multiple additions were constructed later in the century while it was the home of Olmstead Falls postmaster Arthur P. Gray.

[2] Despite its early construction date, just six years after the arrival of the area's first settlers, the partially stone Adams House is built in the Italianate style, which is much more commonly found in buildings from the later part of the century.
