Hajipur, a town of British India, in the Muzaffarpur district of Bengal, on the Gandak, just above its confluence with the Ganges opposite Patna. Pop. (1901), 21,398. Hajipur figures conspicuously in the history of the struggles between Akbar and his rebellious Afghan governors of Bengal, being twice besieged and captured by the imperial troops, in 1572 and 1574. Within the limits of the old fort is a small stone mosque, very plain, but of peculiar architecture, and attributed to Hājī Ilyās, its traditional founder (c. 1350). Its command of water traffic in three directions makes the town a place of considerable commercial importance. Hajipur has a station on the main line of the Bengal and North-western railway.
