The Mother Mosque of America, once known as The Rose of Fraternity Lodge and also known as Moslem Temple, in Cedar Rapids, Iowa, United States, is the longest standing mosque in North America. Built in 1934, it is the second oldest after the 1929 mosque built in tiny Ross, North Dakota, however that mosque was torn down in the 1970s and later rebuilt in 2005, leaving the Mother Mosque as the oldest standing. It is also slightly younger than the Al-Rashid Mosque in Edmonton, Alberta, Canada.
The Mother Mosque is listed on both the Iowa State Historical Register and the National Register of Historic Places as an "essential piece of American religious history, which symbolizes tolerance and acceptance of Islam and Muslims in the United States." It was listed on the National Register in 1996 as Moslem Temple.
