Jat Muslim, or Musalman Jats (Punjabi: مسلمان جٹ; Sindhi: مسلمان جتcode: snd promoted to code: sd ), are an elastic and diverse ethnoreligious subgroup of the Jat people, who follow Islam and are native to the northwestern Indian subcontinent. They are primarily found in the Pakistani provinces of Punjab, Sindh and Azad Kashmir. A small minority is also present in India's Haryana and Western Uttar Pradesh, where they are referred to as Muley Jats.

The Jats began embracing Islam during the medieval period, influenced in part by Sufi teachings. According to the Jawahir-i-Faridi, Jat clans such as the Khokhars, Bhattis, Dhudhis, Hans, Johiyas, and Wattus converted during the time of Baba Farid. The process of conversion was gradual.

The Jats were one of the first communities of the Subcontinent to interact with the Muslims. They were known as the Zuṭṭ (Arabic: الزُّطِّ), although this term also referred to several other groups—such as the Sāyabija, Andāghar, and Qufs—not all of whom were necessarily ethnic Jats. The Zutt were originally from the Indus Valley, but had been settling in lower Iraq since the reign of Bahram V. Following the failed Zutt Rebellion, the Zutt lost their power and distinct identity. They ceased their migrations into Iraq following the fragmentation of the Abbasid Caliphate. The Arabs had noted several agglomerations of Jats settled throughout the province of Sind.

Between the 11th and 16th centuries, some Sindhi Jats migrated up into Punjab. Many clans have traditions of converting to Islam during this period, influenced by Sufis like Baba Farid. By the 16th century, many Punjabi clans west of the Ravi river had converted. Despite conversion, many Jats continued to resist foreign Muslim imperial powers such as the Timurids, Mughals, and Surs. Meanwhile, others chose to cooperate with the Muslim rulers to advance their own interests.

During the Delhi Sultanate, Ghiyath al-Din Tughluq was appointed as the governor of Multan, and later of Dipalpur. His early forces were primarily composed of Jat tribesmen recruited from Dipalpur, who fought alongside him in all his campaigns.

During Mughal rule, Jats came to own considerable land and exert local influence. The Mughals never had direct control over many of these rural grandees. Some also obtained high positions, such as Grand Vizier and Vakil-i-Mutlaq, Saadullah Khan, Faujdar of Sialkot, Rahmat Khan Bajwa, prominent Jagirdar, Rai Muhammad Jani Malhi, and governor of Gujrat, Rehmat Khan Warraich.

As the Mughal empire began to decline, various groups vied to fill the resulting power vacuum. Among them were several ambitious Muslim Jat chiefs and princes. In Rohilkhand, the Rohilla Nawabs established the Kingdom of Rohilkhand and the Rampur State. In the Deccan, a descendant of Saadullah Khan, Muzaffar Jang Hidayat, briefly became the Nizam of Hyderabad. And in Punjab, the Gondal Jats of the Gondal Bar resisted Nader Shah, while the Pakpattan and Chattha states resisted the expanding Sikh Misls. With the establishment of the British Raj, all formerly independent or autonomous polities were either annexed or integrated into the colonial empire as princely states.

During British rule, many Punjabi Muslims, including Jats, would enlist in the British Indian Army. Most were recruited from the Pothohar Plateau.
