Siraj-ud-Din Ali Khan () (1687-1756), also known by his pen-name Arzu, was a Delhi-based poet, linguist and lexicographer of the Mughal Empire. He used to write mainly in Persian, but he also wrote 127 couplets in Urdu. He was the maternal-uncle of Mir Taqi Mir. He taught Mir Taqi Mir, Mirza Muhammad Rafi Sauda, Mirza Mazhar Jan-e-Janaan and Najm-ud-Din Shah Mubarak Abroo. Arzu was born in Agra. He was the son of Sheikh Hisam-ud-Din, a soldier who held many high offices in the court of the Mughal emperor Aurangzeb. He was highly proficient in Persian and Arabic, the two languages which he learned as a child. He also learned Urdu and Sanskrit. Arzu started writing at the age of fourteen, and came to Delhi in 1719. He was introduced to Nawab Qamar-ud-din Khan by Anand Ram 'Mukhlis'. Qamar-ud-Din, who was the prime minister at that time, gave him a suitable job. Arzu used to hold mushairas at his home, and attracted many disciples including Mir Taqi Mir. In 1751, he wrote an Urdu-Persian dictionary called the Navadirul Alfaz. He migrated to Lucknow in 1754, and subsequently to Ayodhya, which was once the residence of his great-grandfather. He died in Lucknow in 1756, and was buried in the Vakilpura area of Delhi.
