Shah Jalal (Persian: شاه جلال‎; Bengali: শাহ জালাল full name:Yamanī Shāh Jalāl ad-Dīn al-Mujarrad) is a celebrated Sufi Muslim figure in Bengal. Jalal's name is associated with the Muslim conquest of north-eastern Bengal and the spread of Islam in Bangladesh through the Sufi Movement. He was buried in Sylhet, Bangladesh,formerly known as Jalalabad, while the country's main airport is named in his honour.

Born Makhdum Jalāl ad-Dīn bin Muhammad, he was named al-Mujarrad (probably for his lifelong celibacy or performing of prayers in solitary milieu) and entitled Shaykh-ul-Mashāykh ("Great Scholar"). Shah Jalal's date and place of birth is not certain. Various traditions and historical documents differ. A number of scholars have claimed that he was born in 1271 CE in Konya in modern day Turkey and later moved to Yemen either as a child or adult while the majority believe he was born in a village called Kaninah in Hadhramaut, Yemen. He was the son of a Muslim cleric, who was a contemporary of the Persian poet and Sufi mystic, Jalal ad-Din Muhammad Rumi but was educated and raised by his maternal uncle Syed Ahmed Kabir in Mecca. He excelled in his studies and became a Hafiz there, increasing proficiency in Islamic theology (aqidah). He achieved spiritual perfection (kamaliyyah) after 30 years of study, practice and meditation.
