MosqueIndex is a free online directory that helps people find mosques and masjids across the United States. Covering all 50 states and the District of Columbia, it features more than 3,100 listings with addresses, maps, and search tools to browse by mosque name, city, or state. Visitors can also filter listings by amenities such as wheelchair accessibility and parking.

The directory provides daily prayer-time estimates calculated for each mosque’s location using the ISNA method, a standard in North America. Community-confirmed Jummah times are included when available, while users are encouraged to verify Friday prayer and iqama schedules directly with each mosque. Listings are sourced from OpenStreetMap, Google Maps place data, and community submissions, and each record identifies its source. Users can submit corrections or add mosque information to help keep the directory useful. MosqueIndex presents itself as free for both visitors and mosques, offering a straightforward resource for locating Islamic centers and checking practical details before a visit.
