Bait-ul-Nasir Mosque, located in Sharon, Massachusetts, serves the Ahmadiyya Muslim Community Boston Chapter. The Boston Ahmadiyya community has been established in the Greater Boston area since the 1960s. Under the guidance of Hazrat Mirza Nasir Ahmad, Khalifatul Masih III, the Community acquired land near Sharon, and in 1997 a mission house was constructed there. The center later became known as Bait-ul-Nasir in memory of Khalifatul Masih III. In June 1997, Hazrat Mirza Tahir Ahmad, Khalifatul Masih IV, visited the newly established center, marking the first visit of an Ahmadiyya Khalifa to Boston.

The mosque continues to serve as the main Ahmadiyya Muslim Community center for the Boston area. Its current address remains 4 Nasir Ahmad Road, Sharon, Massachusetts, as confirmed in the 2026 Ahmadiyya mosque directory.
