The Islamic Center of Louisville, or Fourth Street Mosque, is located in a converted 1882 brick house in the Old Louisville section of town. It was founded in the late 20th century, one of several mosques and Islamic centers to open following the foundation of the Islamic Cultural Association of Louisville in the mid-1970s, the oldest Islamic organization in Louisville.
