Finding a Mosque in the United States
The United States is home to approximately 2,769 mosques — a number that has roughly tripled since 1994 as the American Muslim population has grown. From historic neighborhood masjids founded by immigrant workers in the early 20th century to sprawling modern Islamic centers serving tens of thousands, American mosques are as diverse as the Muslim communities that built them.
Most American mosques offer the five daily congregational prayers (jamaat) and the Friday Jumu'ah prayer, which is obligatory for Muslim men. Many larger Islamic centers also run weekend Islamic schools, women's circles, youth programs, food pantries, and interfaith outreach. If you're new to an area, the local masjid is usually the fastest way into the Muslim community.
Prayer Times vs. Iqama Times
There are two times to know when visiting a mosque: the calculated prayer time (when the prayer becomes valid according to the sun's position) and the iqama time(when the congregation actually begins praying). Most mosques delay the iqama 10–30 minutes after the calculated time to allow worshippers to arrive. The times shown on our city pages are the calculated prayer times. Check the mosque's website or call ahead for iqama times, which vary by mosque.
Jumu'ah (Friday prayer) is different from the other prayers — it replaces Dhuhr and includes a mandatory khutbah (sermon) delivered by an imam. Most US mosques hold Jumu'ah between 12:30 PM and 2:00 PM. Large mosques often run two or three consecutive khutbahs on Fridays to serve their full congregation.
What to Expect When You Visit a Mosque
American mosques generally welcome first-time visitors and non-Muslim guests, particularly at community events and open-house programs. Here is what to know before you go:
- Remove shoes at the entrance. All mosques require shoes to be removed before entering the prayer hall. There is usually a shoe rack at the door.
- Dress modestly. Cover your shoulders and knees. Women who are visiting are not required to wear hijab, though many mosques provide scarves for women who wish to cover. Men should avoid shorts.
- Wudu (ritual washing) is required for Muslims before prayer. Mosques have wudu facilities (ablution areas) with sinks and foot-washing basins.
- Men and women pray separately in most mosques — typically in different sections of the same hall, or on different floors. This is standard practice.
- Phones should be silenced. It is respectful to keep phones on silent during prayer.
Mosque Regions in the United States
Muslim communities are present in all 50 states, but the largest concentrations are in the New York–New Jersey metro area, Michigan's Dearborn–Detroit corridor, the Chicago suburbs, the Houston metro, and the Virginia–DC suburbs. California has major communities across Los Angeles, the Bay Area, San Diego, and the Central Valley.
African American Muslims — descendants of both enslaved Africans who brought Islam to the Americas and 20th-century converts — have historic mosque communities in cities like Philadelphia, Detroit, Chicago, Washington DC, and New York. These congregations predate the post-1965 immigration wave that brought South Asian, Arab, and African Muslims in large numbers.
