Baitus Samee Mosque, Houston, Ahmadi mosque in North Houston, United States.

Baitus Samee Mosque is a 6,500-square-foot Ahmadi Muslim mosque on a 5.5-acre site in North Houston, built for $1.5 million and dedicated in March 2004. Its prayer hall holds 1,000 worshippers, and the grounds provide parking and facilities for visitors.

The project began in 1998 as part of an effort to build mosques in American cities and opened its doors in 2001. This establishment was part of a broader expansion of Ahmadi Islam across the United States.

The community brings together worshippers from Pakistan, Bangladesh, India, Nigeria, and many other countries. The space encourages encounters between different faith groups through regular meetings and open conversations.

The mosque stands on a 5.5-acre site and holds 1,000 worshippers, so it fills during Friday prayers and interfaith events. Its 6,500-square-foot building was raised in stages, with the foundation laid in 1998 and the congregation moving in during 2001. Visitors arriving by car use the on-site parking; the Harris County Sheriff's Office and FBI investigated threats made against the mosque in 2019.

In 2018 the mosque was one of only four stops in the United States by Mirza Masroor Ahmad, fifth caliph of the worldwide Ahmadiyya community, who led prayers and gave his Friday sermon here before continuing to Guatemala. Guests were expected from across the Gulf Coast and abroad.
