ARJAN SIṄGH (d. 1859), a military commander in Sikh times, was born the son of Jamīat Siṅgh of Raṅghaṛ Naṅgal, in Gurdāspur district. In 1845, on the eve of the first Anglo-Sikh war, he was given the command of four infantry regiments, one regiment of cavalry, and a troop of horse artillery, with which force he served at the battle of Sabhrāoṅ. In 1846, he took part in the Kashmīr expedition and in August 1847 received a Persian title of honour on the recommendation of Major Henry Lawrence, the British Resident at Lahore. In 1848, he accompanied Rājā Sher Siṅgh Aṭārīvālā to Multān, and became an ally in his rebellion. His followers, hearing this, rebelled too and defended the fort of Raṅghaṛ Naṅgal successfully against two companies of the Lahore troops. After the annexation of the Punjab by the British, the estates of Arjan Siṅgh were confiscated.

        Arjan Siṅgh died in 1859.
