The Morris Plains Museum's mission is to connect the past to the present and make Morris Plains's vibrant history tangible, relevant, and meaningful for today’s community and for generations to come.

The Morris Plains Museum Association was founded by Borough Historian Muriel Rennie on September 24, 1974. The Association as defined in the certificate of incorporation is a non-profit organization dedicated to the collection, storage, preservation, and display of items relative to the history of the Borough of Morris Plains.

The Museum was first located in a room on the second floor of the Morris Plains Library. Here, Miss Rennie and her staff started recording and displaying items of local history. Through their efforts we have a wonderful collection of pictures, maps, documents, and artifacts. Miss Rennie died in 1992.

Daniel B. Myers was appointed Borough Historian. Under new leadership the Museum expanded to a second room with a storage area on the third floor.

On May 1, 2005, the Museum moved to its present location in the lower level of the Community Center at 51 Jim Fear Drive, Morris Plains. The Museum now has a great facility to fulfill the purpose set forth in the certification of incorporation granted to the Museum Association by the State of New Jersey.
