The Badshahi Mosque (Punjabi: بادشاہی مسیت, romanized: bādśāhī masīt; Urdu: بادشاہی مسجد, romanized: bādśāhī masjid) is a Mughal-era imperial mosque located in Lahore, Punjab, Pakistan. It was constructed between 1671 and 1673 during the rule of Aurangzeb, opposite of the Lahore Fort on the northern outskirts of the historic Walled City. It is widely considered to be one of the most iconic landmarks of Pakistan.

The Badshahi Mosque was built between 1671 and 1673 by the Mughal emperor Aurangzeb. The mosque is an important example of Mughal architecture, with an exterior that is decorated with carved red sandstone with marble inlay. It remains the largest mosque of the Mughal-era, and is the third-largest mosque in Pakistan. In 1799, during the rule of Ranjit Singh of the Sikh Empire, the mosque's courtyard was used for worship. When the British Empire took control of Lahore in 1846 it was used as a garrison until 1852. Subsequently, the Badshahi Mosque Authority was established to oversee its restoration as a place of worship. It is now one of Pakistan's most iconic sights.
