Williams Grove is a historic home located at Berlin, Worcester County, Maryland, United States. It is a two-story, three-part house built in three principal stages. The construction sequence began about 1810 with a two-story, two-bay frame house with a single-story wing, that forms the center of the house. The house was expanded first during the mid 19th century and in the early 1970s, a two-story kitchen and garage wing was added. The exterior is covered with cypress shingles.
Williams Grove was listed on the National Register of Historic Places in 1996.
